| Abstract: | The effects of rare earth elements on the corrosion and corrosive wear resistance of Cr Mn N containing stainless steel were studied. RE elements made the corrosion potentials move towards a positive value, the steady passive current decrease and the thermodynamic stability of the steel increase, so the corrosive resistance and wear resistance of the steel were improved. The optimal addition of RE(%(wt)) for Cr Mn N Containing stainless steel was obtained. This work will provide the necessary technological parameters for producing this kind of stainless steel. |
