Effect of post-oxidizing temperature on tribological and corrosion behavior of plasma nitrided austenitic stainless steel

► Post-oxidation treatment reduces wear resistance of plasma nitrided sample. ► Post-oxidation treatment increases corrosion resistance of plasma nitrided sample. ► Post-oxidation treatment reduces the surface roughness of plasma nitrided sample. ► The amount of S-phase decreases as the post-oxidation temperature increases. ► Increasing oxidation temperature decreases corrosion resistance of oxidized samples.
