Abstract

The corrosion and tribocorrosion behaviors of Type 304 stainless steel coated by two different amorphous carbon films, including undoped and Cr-doped amorphous carbon films, were investigated in HNO3 solution, and bare Type 304 stainless steel was used for comparison. In static-corrosion environment, the corrosion current densities of the carbon-based films were decreased by 41% to 97%, when compared with stainless steel, thus suggesting that the corrosion protection properties of the films were excellent. Tribocorrosion tests were conducted to synchronously monitor the open-circuit potential and friction coefficient of the films, and the friction coefficient increased with the increase of HNO3 concentration. Therefore, the carbon-based films could effectively improve the wear resistance of Type 304 stainless steel in HNO3 solutions.
