摘要Improving the surface properties of a material is an important method that extends the service life of machine parts under harsh condition in multi-environment. In this study, carbon-rich CrC coating was deposited on 316L stainless steel using multi-arc ion plating to improve its protective properties. Due to the formation of binary carbide nanocomposite structure, the hardness and elastic modulus of the coating are up to 30 and 400 GPa, respectively. The tribological behavior of CrC coating and 316L sliding against WC-Co ball under dry friction, the lubrication of distilled water and seawater were comparatively studied. Whatever the conditions, the CrC coating has a more advanced protective performance than 316L. The tribological performances of two samples are not only related to the microstructure and mechanical properties of itself, but also to the lubricating effect and corrosive effect of the medium. Friction coefficients and wear rates of these samples sliding in three different conditions decrease in the following order: dry friction, sliding in distilled water and seawater. As a result, the CrC coating can be treated as a good anti-corrosion material due to its dense and compact structure, chemical inertness to aggressive seawater and formation of oxide passivation layer.
