Nitriding has long been used to engineer the surfaces of engineering steels improve their surface and subsurface properties. The role compound layer (γ′-Fe4N and/or ε-Fe2-3N) in improving tribological corrosion-resistant properties nitrided established. However, there have very few studies on response tribocorrosion corrosive environments. In this work, behavior a 5 μm thick γ′-Fe4N nitride pro...
