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: In this article we report enhanced antifouling properties of reverse osmosis (RO) membranes surface-modified with zwitterionic copolymer films of (poly 4-vinylpyridine-co-ethylene glycol diacrylate) (p(4-VP-co-EGDA)). The copolymer films were deposited onto the surface of RO membranes via an initiated chemical vapor deposition technique (iCVD) followed by a quaternization reaction with 3-bromopropionic acid. XPS analysis revealed that zwitterionic moieties were highly surface-enriched; concentrated in the top ~5 nm of deposited films. Resistance to fouling of the zwitterionic coatings was investigated by determining the extent of biopolymer adsorption via quartz crystal microbalance with dissipation monitoring. The surface-modified quartz sensors exhibited superior resistance to the adsorption of two biopolymers; bovine serum albumin (BSA) and humic acid (HA). Biofouling propensity of the modified RO membranes was further investigated using two bacterial strains abundantly present in seawater. The results showed ~98% lower attachment of both Pseudomonas aeruginosa and Bacillus licheniformis bacteria onto the surface of modified membranes as compared to virgin membranes. Molecular force mapping (MFP) was employed to investigate and quantify interaction forces between model foulant BSA and both bare and modified RO membrane surfaces. The results of MFP revealed that the adhesive force between the foulant (BSA) and membrane surface was at least an order of magnitude lower for the modified membranes when compared to virgin membranes.

    ABSTRACT: This paper is focused on experimental analysis of the effects of laser surface hardening (LSH) combined with subsequent ultrasonic impact treatment (UIT) on the surface microrelief, hardness and microstructure in near-surface layers of AISI D2 high-chromium, cold worked tool steel. The LSH provides fast heating of the near-surface layers to the temperature above that of the phase transformation and temperature then rapidly cools by a self-quenching process. The formed heat affected zone is hardened thanks to the rapid heating/cooling process affecting microstructure, phase composition and carbides formation. Conversely, the UIT induces multiple impact loads providing severe plastic deformation of near-surface layers, and the hardening occurs by a dislocations mediated process. The optimal parameters of each process were determined to obtain maximum hardness and regular surface microrelief. Further, complete analysis of the effect of combined treatment (LSH+UIT) on the surface hardness, microhardness depth profile and surface microrelief was performed. Results show that the combined LSH+UIT process provides almost triple, double and a 10% increase in hardness in comparison with those of the initial, UIT-processed and LSH-treated states, respectively. The surface microrelief, waviness and roughness parameters were respectively diminished after LSH+UIT by approx. 50, 65, and 90%. XRD analysis was carried out after LSH and LSH+UIT processes, which showed essential α-Fe peaks broadening due to the formation of microstrains (0.27% and 0.47%, respectively) and reduction in crystallite size (84 nm after LSH+UIT). Favorable compressive residual stresses (–205 MPa and –409 MPa, respectively) were also observed in the near-surface layers of ~350 and 80 μm thick, respectively. The obtained results demonstrate that combined LSH+UIT process is feasible surface treatment for the quality improvement of the tool steel components including both the surface microrelief and hardness characteristics.

    ABSTRACT: A comprehensive investigation of hard coatings deposited by physical vapor deposition (PVD) requires, in addition to the elastic properties, a precise knowledge of their plastic behavior. Nanoindentation is a commonly applied method to determine the hardness and the elastic modulus of PVD coatings. Determination of flow curve of PVD thin coatings using a combination of nanoindentation and finite element (FE) simulation is subject of current research. In the presented work, nanoindentation tests with a Berkovich tip, in combination with its FEM simulation, were used to determine the plastic flow curves of CrN, AlN and CrN/AlN-multilayer coatings deposited by high power pulse magnetron sputtering (HPPMS) PVD on cemented carbide substrates. The applied FEM model was used to simulate the indentation process. The details of the FEM model and the applied experimental and analytical methods are discussed. The determination of the simulative flow curves was carried out according to the Johnson–Cook model and by finding the coefficients of the considered plastic flow model. The coefficients were determined by comparing the simulated and measured maximum forces, and additionally, by correlating the indentation imprints after nanoindentation tests in simulation and experiment. The correlation was performed by depth profiling of the indentation imprints using confocal laser scanning microscopy (CLSM) and atomic force microscopy (AFM). The plastic behavior of the studied coating systems was analyzed combining the simulated flow curves and the results of the analysis of indentation imprints. The results show a higher resistance of the nanostructured CrN/AlN-multilayer coating against plastic deformation compared to CrN and AlN. This is most likely due to the nm-sized alternating layers and the fine grained morphology of the CrN/AlN-multilayer compared to the pure coatings, which hinders the dislocation motion.

    ABSTRACT: Aluminum, and particularly its alloys, are the materials of an increasing significance in construction and automotive industry due to the combination of their strength properties. However, their functionality is limited mainly because of the susceptibility on tribologicalwear. This paper presents the results of the study aimed at determining the optimumconditions of the process of alloy surfacemodification with N+ ions in the atmosphere ofN2–H2, using the method of chemical precipitation from gaseous phase, combined with a discharge of a frequency of 13.56MHz (radio frequency chemical vapor deposition). It was demonstrated that the process of Al–Zn alloy surface modification with nitrogen ions is a necessary prerequisite to obtain low-friction coatings (SiCNH in this case) characterized by a good and stable adhesion to the aluminum alloy substrate. The highest hardness is obtained in the case of SiCNH coating deposition process, preceded by the process of surface modification in plasma conditions, provided for N2 only (hardness 10.0 GPa) of the N2/H2 mixture (flow ratio 3/1, hardness 10.5 GPa). The surface of alloy combined with the obtained DLC (diamond-like carbon) layers, doped with N and Si atoms is characterized by ca. 30% decrease in the friction coefficient value (up to the 0.2 value) and ca. 25% decrease in the value of surface roughness (Ra, 6.5 nm), compared to unmodified substrates.

    ABSTRACT: In thermal spraying, adhesive bond strength is a feature of surface properties. An adapted surface is studied with prior-surface treatments to enhance interface energy. This study deals with Ni-Al coatings on 2017 Aluminum alloy substrate produced by atmospheric plasma spraying. The adherence was evaluated with several controlled surface topographies obtained by grit-blasting and laser surface texturing technique. Adherence has been tested with two different techniques: Pull-off test and LASer Adhesion Test. They induce different stresses at the interface. The results showed that the adhesive strength is mostly controlled by a contact adhesion area. A large contact area increases the energy release rate at the interface during coating failures. The bond strength tendency for the two adherence tests is similar: apparent adherence is tripled thanks to laser surface patterning. Fracture propagation is stopped nearby laser-induced holes due to the complex shape and has to deviate inside the coating to maintain crack propagation (inter-splat cracks). The energy at the interfaces being stored locally due to pattern: pattern morphology, pattern localization and powder feed rate are important factors that control the adhesion strength of the thermally sprayed coatings.

    ABSTRACT: With regard to the transportation sector, an efficient powertrain technology contributes to sustainable lowering of CO2 emissions. Due to the periodic or continuous operation in boundary and mixed friction, minimization of friction losses in automobile gearboxes offers massive potential in terms of efficiency improvement and saving fossil fuels. In close cooperation between the Surface Engineering Institute (IOT) and the Gear Research Center (FZG), the aim of this work was to reduce friction losses in powertrain by diamond-like carbon (DLC) coatings on highly loaded gears under severe rolling–sliding conditions. The zirconium based DLC coatings ZrCg (a:C-H/ZrCg) and nanocomposite ZrC (a-C:H/ZrC) were deposited by physical vapor deposition (PVD) at IOT. The industrial DLC coating DLC-REF1 served as reference. Application-related tribological tests of lubricated highly-loaded rolling–sliding contacts were performed in a twin-disc test-rig and a gear efficiency test-rig at FZG. Calculations and measurements of relative lubricant film thickness confirmed that the tribological model tests covered the entire friction regime from boundary and mixed friction to fluid friction (elasto-hydrodynamic lubrication, EHL). Despite complete separation of the coated surfaces, the Coefficient of Friction was reduced by 35% using ZrCg coated discs in the twin-disc test-rig. Practical investigations of DLC coated gears in the FZG gear efficiency test-rig revealed that compared to uncoated gears friction losses in EHL were reduced by up to 25% using the industrial reference DLC-REF1 and 39% using ZrCg, especially at higher loads and higher circumferential speeds. This yet widely unknown favorable effect of DLC coatings under EHL conditions was attributed to the thermophysical properties of DLC coatings and confirmed by simulations of real rolling–sliding contacts at FZG. Wetting analyses of tribological surfaces were analyzed determining the surface properties, interfacial tension and surface energy, of the DLC coatings and the gear oils by means of contact angle measurements. The adhesion energy was calculated from contact angle data. Correlation analyses revealed a clear impact of the interfacial tension and adhesion energy on the frictional behavior under boundary and fluid friction conditions. It was found that a higher adhesion energy (good wetting) contributes to a lower CoF under boundary and mixed friction conditions as well as in the fluid friction regime (EHL).

    ABSTRACT: Carbon based coatings are well established in the automotive industry to solve tribological problems in automotive applications. In systems under high load and/or high contact pressures, these coatings are used to reduce friction and wear. Other coatings like chromium nitride are useful to prevent scuffing. However, a real challenge in evaluating coatings for their suitability in automotive applications is the broad range of conditions which defines the load collective of the tribological system. In this work, we focused on the thermal effects that might influence the stability and performance of coatings in tribological applications. In a car engine, the temperature range might be much broader than the -20°C to 120°C as given by the average oil temperature. In the tribological contact zone the temperature can be higher up to several hundred degrees Celsius, especially if it comes temporary dry running due to starved lubrication. These locally high temperatures can affect the properties of a coated surface, but the coated surface itself might also have an influence on the temperature in the contact zone. This is especially the case, if coatings with low thermal conductivities like carbon based materials are used. Therefore, we focused our here presented work on the investigation of the influence of the temperature on the wear performance, the friction coefficient and the thermal stability of a DLC coating in unlubricated conditions. The DLC coating was submitted to dry running reciprocating sliding wear tests in a broad temperature range and then the thermal stability of the coating has been analyzed by means of hardness measurements (nanoinentation) and a structural approach (Raman spectroscopy). In addition, we analyzed the effect of a DLC coating on the tribological properties of a lubricated contact on a two-disc tribometer. These efforts were completed by measurements of the thermal conductivity of the DLC coating.

    ABSTRACT: High frequency anodising of Al-TiO2 surface composites using pulse reverse pulse technique was investigated with an aim to understand the effect of the anodising parameters on the optical appearance, microstructure, hardness and growth rate of the anodic layer. Friction stir processing was employed to prepare the Al-TiO2 surface composites, which were anodised in a 20 wt.% sulphuric acid bath at 10 °C as a function of pulse frequency, pulse duty cycle, and anodic cycle voltage amplitudes. The optical appearance of the films was characterized and quantified using an integrating sphere-spectrometer setup, which measures the total and diffuse reflectance from the surface. The change in optical reflectance spectra from the anodised layer was correlated to the applied anodising parameters and microstructure of the anodic layer as well as the Al-TiO2 substrate. Change in hardness of the anodised layer was also measured as a function of various anodising parameters. Anodic film growth, hardness, and total reflectance of the surface were found to be highly dependent on the anodising frequency and the anodic cycle potential. Longer exposure times to the anodising electrolyte at lower growth rates resulted in lowering of the reflectance due to TiO2 particle degradation and low hardness due to increased dissolution of the anodised layer during the process.

    ABSTRACT: The role of bond coat (BC)–thermal barrier coating (TBC) interfacial morphology on the failure of yttria-stabilized zirconia (YSZ) air plasma sprayed (APS) thermal barrier coatings on a NiCoCrAlY bond coat has been investigated. Interfacial morphology plays a key role in the generation of compressive and tensile stresses normal to the global surface plane through oxide growth processes and microstructural evolution, but a functional correlation between BC morphology and coating lifetime for these systems has proved to be elusive. A compilation of quantitative surface morphology parameters – average roughness (Sa), areal root-mean square slope (Sdq), and areal summit density (Sds) – have been assembled to provide a lifetime-relevant description of interfacial morphology, relative to observed coating failure mechanisms. Current data suggest that a combination of the following BC–TBC morphology parameters have a positive effect on coating system lifetime: (1) an average roughness of 15 μm ± 3 μm, (2) a slope distribution with a summit near 66° ± 3°, and (3) a peak-to-peak summit spacing of approximately 120 μm ± 10 μm. The observed increases in coating lifetime are attributed to the increased effective toughness of the TBC microstructure as a direct result of the morphology of the BC onto which the TBC is sprayed.
