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 in H₂O₂ solutions with different concentrations. Corrosion current densities (CCDs), coefficients of frictions (COFs), wear mass losses, wear surface topographies, and metal oxide films were analysed and compared. The results show that the wear process and oxidation process interacted significantly with each other. Increasing the concentration of H₂O₂ or the oxidation time was useful to form a layer of integrated, homogeneous, compact and
