Effects of Plasma-Nitriding on the Surface Characteristics of Stainless Steels Containing Nb

Nb함유 스테인리스강의 표면특성에 미치는 플라즈마질화의 영향





Abstract

In order to develop the corrosion and wear resistance of stainless steels, effects of plasma-nitriding on the surface characteristics of stainless steels containing Nb were investigated by utilizing a potentiostat. It was found that plasma nitriding at $350^{circ}C$, compared with $500^{circ}C$, produced a good corrosion resistance as nitriding time increased, whereas stainless steel containing low Nb content showed that pitting potential and corrosion potential decreased.
