Publisher: Elsevier

Journal description

The increasing requirement for high technology materials with specific performance characteristics in various types of environments has dictated that these materials possess near-surface properties different from their bulk properties. Surface and Coatings Technology is a principal forum for the interchange of information on the science, technology and applications of thin and thick coatings and modified surfaces which alter the properties of materials. The scope includes all types of coatings and surface modification techniques (including physical vapour deposition, chemical vapour deposition, electroplating and surface modification by directed energy techniques). Of particular emphasis are the emerging advanced processes such as thermal spraying, sputter deposition, activated reactive evaporation, ion plating, molecular beam epitaxy, ion implantation and pulsed laser surface deposition. Contributions range from original scientific articles concerned with applied research or direct applications of coatings to reviews of current technology in specific areas. Articles are solicited on topics which include one or more of the following areas: (1) characterization of coatings and modified surfaces, which includes the determination of composition, structure, adhesion, and internal stresses; (2) the application of coatings and modified surfaces to alter the mechanical, chemical or optical properties of materials. Mechanical properties include friction, wear, erosion, hardness and load bearing capacity. Chemical properties include corrosion and oxidation. Optical and electro-optical properties include reflectivity, selective absorption and electroluminescence. Particular emphasis is also placed on the emerging surface engineering technologies and coatings with a diversity of applications such as diamond, diamond-like carbon, and cubic borin nitride. Other interdisciplinary areas include thermal barrier coatings and coatings for biomedical applications, materials conservation, and environmental applications. Technical Notes are also solicited for the Current Industrial Practices section which is intended for more engineering-oriented articles which should include, for example, developments of coatings deposition equipment (including production systems) and cost/benefit analysis for specific types of coatings.

    ABSTRACT: Low infrared emissivity coating with good thermal resistance was prepared by using Ni20Cr alloy particles and inorganic silicate as pigments and binders, respectively. The effects of size, shape, and annealing temperature of Ni20Cr alloy particles on infrared emissivity of the coatings were systematically investigated. The results indicate that the composite coatings can exhibit low emissivity (0.49) and good thermal stability property. Ni20Cr alloy particles with tens of micron-sized, flaky, and fine crystal structure can be propitious for decreasing the infrared emissivity of the composite coatings. In addition, the thermal stability properties of the composite coatings were measured in air to explore the effect of high-temperature environment on the infrared emissivity. The measured results show that the composite coatings can exhibit a favorable thermal stability property below 800 °C and still possess low emissivity when the test temperature is below 500 °C, due to the Si–O–Si cross-linking network structure and the mechanical interlocking between the coating and substrate.

    ABSTRACT: Nb and CeO2 modified Co-based coatings were produced on 45 steel by plasma cladding. The effect of Nb and CeO2 on microstructure, tensile property and high temperature abrasive wear resistance was investigated. Results indicate that γ-Co, Cr23C6 exists in all coatings, and NbC forms in the Nb-contained and Nb/CeO2-contained cladding coatings. Co-based coating has a fine columnar crystal and dendritic microstructure, finer grain size and equiaxed dendrites are obtained by adding Nb/CeO2. The introduction of Nb and CeO2 reinforcements shows a positive effect on the tensile property due to purification and grain refinement. Tensile fracture mechanism of the composites is primarily controlled by particle cracking as a result of effective load transfer from matrix to the reinforcements. A relatively high temperature wear resistance occurs with Nb and CeO2 modification due to the distribution of high hardness carbide NbC in the clad coating as well as the dense and uniform microstructure.

    ABSTRACT: The protection of the zirconium alloy by Cr3C2–NiCr coating has been evaluated. The corrosion resistant carbide-based cermet coatings were deposited on the zirconium alloy substrate using high velocity oxygen fuel technique and were exposed to high-temperature air and steam environment from 700 °C to 1000 °C. To examine the performance of the coating in supercritical water, the coating was tested in autoclave at 400 °C/10.3 MPa for 72 h. The thermal shock experiments were conducted to examine the bonding of the coating. It was suggested that the coating encompassing compatible electronegativity and thermal expansion coefficient with zirconium alloys and favorable toughness could be selected as a candidate for fuel cladding protection layer.

    ABSTRACT: The effects of substrate roughness on the wettability of non-reactive wetting and compound forming wetting systems were investigated by the sessile drop technique at high temperature. The AgCu eutectic alloy/copper and the AgCuTi/alumina wetting systems were selected. It is found that the substrate roughness has a great effect on both wetting systems. For the non-reactive wetting system, an additional capillary driving force exists when melt flows into the micro v-grooves of the rough surface, leading to a decrease in final contact angle (θf) and consequently a better wettability. For the compound forming metal/ceramic reactive wetting system, wetting on a rough surface exhibits a slow spreading kinetics and a short period of spreading time, and the retarding force of spreading increases because of overcoming the energy barriers due to asperities of the rough surface, resulting in an increase in θf. Thus, a rough substrate has negative effect on the wettability of the compound forming reactive wetting system.

    ABSTRACT: WCN coatings with carbon content ranging from 0 to 19.2 at.% were deposited by reactive magnetron sputtering technique. The structure, mechanical, tribological properties and corrosion performance were investigated by XPS, XRD, SEM, HRTEM, nano-indentation CSM, ball-on-disk tribo-meter, AFM, Bruker 3D Profiler and corrosion testers. The results show that the incorporation of carbon does not affect the cubic structure. WCN coatings consist of WCN and amorphous C and CNx phases. The incorporation of carbon results in the crystallite size refinement and the decrease of the average roughness. The H, H/E and H3/E2 ratios of WCN coatings first increase and then decrease and the maximum values are 36.7 GPa, 0.110 and 0.30 GPa, respectively, at 14.8 at.% C. All the H, H/E and H3/E2 ratios of WCN coatings are higher than that of W2N coating. The friction coefficient and wear rate of WCN coatings first decrease and then increase with increasing the carbon content. The friction coefficient and wear rate are mainly related to the lubricant wear debris. Moreover, the hardness and the ratios of H/E and H3/E2 also have a certain influence on the wear rate of the coatings. The corrosion resistance of the substrate which coated with W2N or WCN coatings is superior to the bare substrate. The corrosion resistance of the W2N coating is improved by doping some carbon content.

    ABSTRACT: Germanium antimony tellurium (GeSbTe) thin film has been deposited by the RF magnetron sputtering from the initial material target of the 1:1:1 atomic ratio. The GeSbTe thin film was annealed by furnace at 473 K, 523 K, 573 K and 623 K samples for 1 h under ultra-high vacuum. The samples were analyzed by X-ray diffraction (XRD), field-emission scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) to study their structure and chemical composition. The carrier concentration, charge mobility, electrical, Seebeck coefficient and power factor are reported. The as-deposited thin film showed amorphous and consequently cubic structure (c-GeSbTe) after annealing treatments. In addition, the film thickness was rapidly decreased with increasing annealing temperature. The as-deposited thin film had the atomic ratio of 1:0.6:0.7, and after annealing treatments became 1:0.9:0.9. The c-GeSbTe thin film annealed at 523 K showed the highest mobility, lowest electrical resistivity, and the highest power factor of 8.31 cm2 V− 1 s− 1, 3.25 × 10− 5 Ω m, and 0.81 × 10− 4 W m− 1 K− 2, respectively.

    ABSTRACT: Laser treatment of alumina surfaces is carried out under high pressure nitrogen assisting gas ambient to generate a selective surface in relation to solar heating applications. Laser treated surfaces are sol–gel coated for protection from the dust settlements and the mud formation in the humid air environments. Morphological and metallurgical changes in the laser treated layer are examined using analytical tools incorporating scanning electron microscope (SEM), atomic force microscope (AFM), energy dispersive spectrometer (EDS), and X-ray diffraction (XRD). The optical characteristics of the sol–gel coating are assessed by incorporating ellipsometer. The residual stress formed in the laser treated layer is determined from X-ray (XRD) and Fourier transform infrared spectroscopy (FTIR) data. The influence of the mud, formed from the dust particles, on the surface characteristics of laser treated, and laser treated and sol–gel coated surfaces are examined and the adhesion work required to remove the dry mud from the surfaces are determined from the tangential force data obtained from micro-tribometer. The findings revealed that the laser treated and sol–gel coated alumina surfaces provide superior surface characteristics in the harsh environments because of weak adhesion between the mud formed from the dust particles and the coating surface. This is associated with the small texture height of the sol–gel coating, which lowers the area of the interfacial contact between the mud and the coated surface, and relatively lower surface energy of the sol–gel coating as compared to that of the laser treated surface. The sol–gel coating does not alter the optical characteristics of the laser treated surface.

    ABSTRACT: Multilayers of polyaniline (PAni) and PAni/nanotubes-TiO2 composite were compared for corrosive protection on carbon steel and welded carbon steel. The layer porosity, morphology and thickness were characterized. PAni coating showed the best protection when a layer of 2 μm was deposited on steel surface. In spite of the good anticorrosive behaviour of PAni, when the layer thickness was increased up to 4.5 μm a decrease in the anticorrosive behaviour is detected due to the development of mechanical tensions which increase the porosity of the film. However, the addition of TiO2 nanotubes to PAni coatings shows an interesting ability to inhibit this undesirable mechanical effect, showing a good anticorrosive behaviour and lower porosity when thickness layer is increased. The morphological and electrochemical tests of the samples showed good resistance against degradation in chloride medium and in the salt spray analysis, promoting improvement of corrosion protection in an aggressive corrosion medium.

    ABSTRACT: The microstructure and corrosion resistance of a Zn – 4.8 wt.% Al alloy, typically used for high performance galvanised coatings for construction, was modified by the application of ultrasound during solidification. The alloy exposed to ultrasound had an increased volume fraction of smaller, discrete primary η Zn phase regions that were more uniformly distributed throughout the casting. The morphology of η Zn was altered from dendritic to globular and the Zn/Al eutectic growth was disrupted in localised areas from lamellar to anomalous. These changes were likely due to the physical action of the ultrasound disrupting compositional effects, fragmenting dendrites and through the development of cavitation events causing disruptive mixing. These microstructural changes produced an enhanced cut-edge corrosion resistance of the alloy in 0.1% NaCl when coupled with steel mimicking in service coating conditions that was investigated using the SVET. The primary η Zn crystal regions were focussed sites for anodic Zn dissolution and the smaller η regions produced by ultrasound reduced the corrosion rate by preventing the development of crevice like phenomena that may be associated with larger dendrites. The number and size of primary η Zn regions affected the corrosion rate with reductions in these factors reducing the corrosion rate of the alloy.

    ABSTRACT: Boron nitride (BN) coatings were synthesized on silicon carbide (SiC) fibers by a modified dip-coating method using boric acid and urea as BN precursors and acrylamide as gel-casting monomer heated at 850 °C for 3 h under N2 atmosphere. For comparison, a conventional dip-coating method was also adopted to prepare BN coatings under the same conditions. The structure of BN coatings was characterized by X-ray diffraction, Fourier transform infrared spectroscopy and transmission electron microscopy. The morphology of the fibers after impregnation and heat treatment was observed by the electron micrographs. Fiber tensile strength was evaluated by single fiber tensile test. The effects of polyacrylamide on the formation of BN coatings were also investigated. The results show that the BN coatings, prepared by two cycles of impregnation in the modified dip-coating process, covered the SiC fibers well, and exhibited a compact turbostratic–amorphous hybrid structure with a thickness of 550 nm. The tensile strength of the coated SiC fibers increased by ~ 22% after the conventional dip-coating method was modified. The introduction of the sol–gel process enabled the BN precursors to form a film on the surface of SiC fibers with an even distribution in the impregnation process and to retain the evenness in the heat treatment process. Based on the two effects, the conventional dip-coating method was improved.

    ABSTRACT: Bioresorbable magnesium alloys are currently being investigated as implant materials to address the problems associated with traditional metallic implants. However, the use of magnesium in vivo has been limited due to its rapid corrosion in the presence of body fluids. This can result in the liberation of large amounts of hydrogen gas and alkalisation of the body fluid which, in turn, can inhibit wound healing and ultimately lead to necrosis of the surrounding tissue. Calcium phosphate coatings such as hydroxyapatite have been shown to reduce the corrosion rate of magnesium in vivo. Due to the low melting point of magnesium (≈ 600 °C) conventional high temperature techniques to deposit hydroxyapatite, such as plasma spray, are not suitable. This paper investigates the deposition of a hydroxyapatite coating onto the surface of three bioresorbable magnesium alloys using an ambient temperature, blast coating technique. The effect of the coating on the corrosion rate of the alloys in vitro is examined. The coated samples were examined using variety of techniques: x-ray diffraction (XRD), microscopy, elemental mapping, surface roughness and coating adhesion. The corrosion of the alloys was examined using an immersion testing, potentiodynamic polarization and electrochemical impedance spectroscopy. The coatings exhibited high bond strengths (≈ 48 MPa) with no detectable change in the coating's crystallinity after deposition. Each of the coated samples displayed lower corrosion rates than the uncoated equivalent sample. The results indicate that the process can be used to produce highly adherent coatings that decrease the corrosion rate of the alloys in vitro.

    ABSTRACT: Laser surface alloying technology was used to improve the fatigue wear resistance of gray cast iron. Comparative studies among the specimens with Cr or WC addition, with the Cr + WC addition and without addition were experimentally investigated. The strengthening mechanism of unit with Cr or WC addition was revealed by means of EDS. After fatigue wear tests, the improved level of fatigue wear resistance was assessed in light of the average mass loss of each group and the defects on various regions were significantly investigated and compared. A finite element method was carried out under laboratory conditions to illuminate the stress distribution on specimens' surfaces and the magnitude of contact stress along contact line. The results of fatigue wear test and finite element calculation were used to account for the fatigue wear resistance mechanisms.

    ABSTRACT: Iron–tungsten with satisfactory corrosion properties is a promising alloy to replace hard chromium. In this work, Fe–W amorphous coatings were prepared by electrodepositing from an aqueous solution and a subsequent heat treatment at 400 °C, 500 °C, 600 °C, 700 °C and 800 °C, respectively. Corrosion behavior of the coatings deposited on copper substrates was studied using potentiodynamic polarization and impedance spectroscopy techniques in 0.1 mol·L− 1 aqueous NaCl solution. As the annealing temperature raises the corrosion resistance of Fe–W coatings increases, and reaches the maximum at 500 °C and then shows a converse variation after 500 °C. This might relate to the surface reconstruction both on the morphology and the chemical oxidation.

    ABSTRACT: Sealing effect of phytic acid (PA) on the sulfuric acid anodized aluminum was studied by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), scanning Kelvin probe (SKP), SEM and EDS. Unsealed anodized aluminum displayed a porous structure and had poor corrosion resistance. The pores were not only filled, but also a PA conversion film with 3–4 μm was formed when anodized aluminum was immersed in 2.5 wt.% PA solution with pH of 1.5 for 15 min at 90 °C. Anodized aluminum with PA sealing exhibited better corrosion resistance, compared to the anodized aluminums sealed by boiling water and dilute CrO3 solution.

    ABSTRACT: A compact Al-enriched and fluoride-containing surface layer can be fabricated on Ti–50Al by anodizing in ethylene glycol (EG) solution containing 1.8 vol.% ionic liquid named 1-butyl-3-methylimidazolium hexafluorophosphate (BmimPF6). After high temperature oxidation, an Al2O3 layer is formed on the thin anodic oxide film (AOF) coated Ti–50Al, which efficiently inhibits the diffusion of oxygen and leads to excellent high temperature oxidation resistance. As a result, after oxidation in air at 1000 °C for 100 h, the anodized Ti–50Al shows a very low weight gain of 0.54 mg/cm2, while the weight gain of bare Ti–50Al is as high as 82.40 mg/cm2. The surface morphology and composition of AOF coated Ti–50Al before and after high temperature oxidation were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and glow discharge optical spectroscopy (GDOS). The results show that the excellent high temperature oxidation resistance of the AOF coated Ti–50Al can be ascribed to two aspects. One is the Al-enriched structure formed initially during anodization, which can inhibit the diffusion of oxygen into the substrate. The other one is the halogen effect. The fluorides introduced into the AOF during anodization promote a selective transport of aluminum from the substrate to the alumina scale/substrate interface through pores or micro-cracks due to the formation of gaseous aluminum fluorides. These aluminum fluorides are then oxidized to Al2O3 at the interface and within the alumina scale. Finally, a protective alumina scale is formed and provides excellent high temperature oxidation resistance.

    ABSTRACT: The effects of plasma current density on phase formation of plasma nitrided H13 steel, and on the consequent tribological properties were investigated. The combination of plasma current density and sample temperature formed several different phases, whose relative abundance influenced the friction and wear behaviors. The phases were identified using conversion electron Mössbauer spectroscopy and grazing incidence X-ray diffraction. Elemental depth profiles were determined with glow discharge optical emission spectroscopy and nuclear reaction analysis. The coefficients of friction and the dimensional specific wear rates were evaluated in pin-on-disk tests. Reduction of the coefficient of friction in the initial stages of the tests was attributed to the presence of cementite, formed in certain conditions of plasma processing. Specific wear rates were quantified with profilometry of the wear scars and indicated ten times lower values, when compared to the non-nitrided samples.
