摘　　要：用电化学方法研究了C15不锈钢的点蚀电位和缝隙腐蚀行为。结果表明:在30℃的3.5%NaCl溶液中,C15不锈钢的自腐蚀电位和点蚀电位均高于对比材料316L和1Cr18Ni9Ti不锈钢的;C15不锈钢缝隙试验用试样在施加0.8V(SCE)恒电位条件下不发生腐蚀。The pitting potential and crevice corrosion behavior of C15 stainless steel were investigated by electrochemical measurements. The results show that the corrosion potential and pitting potential of C15 steel were higher than those of contractive materials of 316L and 1Cr18Ni9Ti stainless steels in 3.5% NaCl solution at 30 ℃. The corrosion of specimen for crevice corrosion of C15 steel did not occur obviously at applied potential of 0. 8 V （SCE）.
