Abstract
The anodic behaviour of sintered austenitic stainless steel was investigated on an analogical system using wrought plate stainless steel of Type 316. Potentiodynamic polarization measurements were carried out on wrought plate stainless steel of Type 316 in an analogical concentration cell using a special method. The effect of carbides precipitation on the anodic behaviour was investigated on carburized 316 wrought stainless steel containing an average carbon concentration of 0.06 and 0.15 (wt. %). The carburization treatment results in an increase in the critical current density although a clear active passive transition is observed. The anodic behaviour of sintered stainless steel in H2SO4 solution is mainly affected by the existence of interconnected open pores. The local intergranular sensitivity to the corrosive environment is increased due to carbide precipitation.
