This paper introduces a self‐built loop multiphase flow‐accelerated corrosion apparatus that can simultaneously conduct In‐Situ electrochemical testing and visualization observation of flow field under various flow state environments. The testing results indicated that environment parameters of pipeline system can be accurately adjusted. The common...

Antibacterial alloys are designed to mitigate biofouling, which is a strategy for combining the defense and function properties of alloys in complex biological environments. However, the current approaches are unable to overcome the issue of microbiologically influenced corrosion (MIC), because antibacterial performances mostly benefit from the exc...

A multi-factor coupled model for stress corrosion crack growth rate in HP-13Cr stainless steel was developed using direct current pressure drop method. Measurements were conducted to investigate the critical stress intensity factor in various well depth environments. The single-factor model for stress corrosion crack extension rate, considering tem...

Artificial liquid‐repellent surfaces are highly desirable to combat pervasive biofouling and corrosion in biological environments. However, existing strategies often suffer from slow binding kinetics and harsh fabrication conditions, hindering the concurrent integration of liquid repellency, universal adhesion, and robust flexibility. Herein, we re...

Microbiologically influenced corrosion (MIC) of engineering structures poses significant safety risks, particularly in environments where sulfate‐reducing bacteria (SRB) are prevalent. In this study, a highly stable hydrosol with strong antibacterial properties is developed by adsorbing hydrophilic groups of polymer chains onto the Cu‐Ag bimetallic...

The effect of intermetallic particles on the corrosion of 6061 aluminum alloy and its coating used in semiconductor processing systems was systematically studied via liquid and gas experiments and micromorphology characterization. The results revealed that a huge difference of corrosion resistance between imported and domestic 6061 aluminum alloys...

This study focused on analyzing the changes in the microstructure and composition evolution of plasma electrolytic oxidation (PEO) and electroless copper–PEO composite (Cu/PEO) coatings both prior to and following irradiation. Additionally, the corrosion resistance and tribological properties of these coatings were assessed. Post-irradiation, the P...

The dense passive film on 316 L stainless steel is the key in its corrosion resistance. Its interactions with an electroactive biofilm are critical in deciphering microbial corrosion. Herein, an in‐depth investigation using genetic manipulations and addition of an exogenous electron mediator found that extracellular electron transfer (EET) mediated...

Purpose The marine environment presents a great challenge to the anticorrosion properties of organic coatings applied on equipment. Since the compactness of coatings is critical in marine environments, a novel nepheline-epoxy resin (N-EP) composite was introduced into organic coatings to improve the interfacial compatibility between the pigments an...

Purpose The purpose of this paper was to compare the electrochemical homogeneity of AZ91D after various heat treatment processes, and its influence on the growth, composition, microstructure and corrosion resistance of phosphate conversion coatings. Design/methodology/approach The electrochemical activity of different heat-treated Mg alloys was ev...

Nickel-based alloys applied in marine environments often face multiple challenges of stress, corrosion and wear. In this work, heterostructured NiCrTi alloy was prepared by spark plasma sintering coarse Ni20Cr and ultrafine Ti powders. Apart that some are dissolved into the nickel alloy, Ti powders react in situ with Ni20Cr during sintering to form...

Aluminide coatings were prepared by chemical vapor deposition (CVD) method on Ni-based superalloy Mar-M247 to improve the corrosion resistance. The Na2SO4-induced hot corrosion behavior of Mar-M247 with and without aluminide coating was investigated at varying temperatures. The results revealed that the substrate underwent relatively mild corrosion...

Surface coatings are designed to mitigate pervasive biofouling herald, a new era of surface protection in complex biological environments. However, existing strategies are plagued by persistent and recurrent biofilm attachment, despite the use of bactericidal agents. Herein, a chiral metal–organic framework (MOF)‐based coating with conformal micros...

To enhance the long-term corrosion resistance of the plasma electrolytic oxidation (PEO) coating on the magnesium (Mg) alloy, an inorganic salt combined with corrosion inhibitors was used for posttreatment of the coating.

The galvanic corrosion performance of AM60B coupled to DC01 was characterized in simulated environments with varying water salinity. The results showed that the coupled DC01 effectively accelerated the corrosion rate of AM60B, and the increased salt concentration had a significant effect on the deterioration process.

Short-time oxidation behavior of nanocrystalline Ta coating is studied at 850 °C in comparison with that of the Ta sheet. Owing to the large PBR value and insufficient expansion space, the oxide scale on Ta sheet is dramatically cracked, delaminated and pulverized, resulting in rapid deterioration. For nanocrystalline Ta coatings with columnar stru...
