摘　　要：通过盐雾试验和点腐蚀电位测试,对比了新型940X不锈钢和9Cr18不锈钢的耐蚀性能。结果表明,在NaCl溶液中940X不锈钢的耐全面腐蚀和耐点腐蚀的性能比9Cr18的高。并结合化学成分及金相能谱分析了940X不锈钢的耐蚀机理。The corrosion resistance of stainless steels 940X and 9Cr18 was investigated by salt spraying tests and pitting potential measurements. Results show that the general corrosion and pitting corrosion resistance of stainless steel 940X was better than that of stainless steel 9Cr18. The mechanism of corrosion resistance of stainless steel 940X was also discussed based on SEM and EDS analyses.
