Coupling mechanism between wear and oxidation processes of 304 stainless steel in hydrogen peroxide environments

Abstract Stainless steel is widely used in strongly oxidizing hydrogen peroxide (H2O2) environments. It is crucial to study its wear behaviour and failure mode. The tribological properties and oxidation of 304 stainless steel were investigated using a MMW-1 tribo-tester with a three-electrode setup...
