| Abstract: | The effect of addition of 7.02%11.98% nickel on crevice corrosion behaviour of Type 304 stainless steel has been investigated with immersion test and electrochemical measurement techniques in 0.3%NaCl solution. The results showed that the addition of nickel increased the repassivation potential for crevice corrosion ( E R), decreased the product of number of sites attacked, N and average value of maximum depth, BX]D(ND) and prevented the active dissolution, improving the resistance to crevice corrosion for Type 304 stainless steel. The AES and XPS analysis indicated that nickel was rich in surface film and transition zone, also existed as NiO in film. The joint effect of chromium and nickel improved electrochemical behavior and the stability of film.= |
