Abstract

Various protective coatings are applied to marine components to mitigate friction, wear, corrosion, and biofouling. However, these issues can arise simultaneously under certain operating conditions, posing significant challenges to the performance and durability of marine components. In this study, core-shell structured WC-Co-Cr/Cu powders were fabricated using electroless plating, and a high-velocity oxygen-fuel (HVOF) spraying technique was employed to deposit the WC-Co-Cr/Cu coating. The results demonstrated that the tribo-corrosion behavior of the WC-Co-Cr/Cu coating improved compared to that of the HVOF WC-10Co-4Cr coating, although there was a slight reduction in corrosion resistance. Additionally, the incorporation of Cu significantly reduced the adhesion rates of Bacillus subtilis and Phaeodactylum tricornutum, indicating that the WC-Co-Cr/Cu coating gained anti-biofouling properties from the presence of Cu. Overall, the development of this WC-Co-Cr/Cu coating presents a promising solution for marine components, providing enhanced tribo-corrosion performance and effective anti-biofouling properties.

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
