摘要
用电化学测试技术研究了不同敏化处理的３０４不锈钢的耐孔蚀性能，探讨了Ｃｌ－浓度、温度和ｐＨ值对孔蚀电位Ｅｂ的影响。结果表明，敏化热处理导致Ｅｂ值下降；随Ｃｌ－浓度增加，介质温度升高，ｐＨ下降，使Ｅｂ值变负；
The pitting corrosion resistence of different sensitized 304 stainless steels was investigated by means of electrochemical technology. The effect of NaCl concentration, temperature and pH on pitting potential (E b) was discussed. The results indicate that sensitization leads to E b decrease. Increasing NaCl concentration and temperature or decreasing pH shifts E b to more negative values. The intergranular corrosion of stainless steel makes pitting corrosion resistence worse.
