摘要
通过动电位扫描和慢应变速率拉伸试验及Ｘ射线能谱技术，研究了Ｈ２Ｓ和钢铁所形成的硫化物膜对ＵＮＳＧ１１１８０钢在含５％ＮａＣｌ的溶液中均匀腐蚀和应力腐蚀的影响．研究结果表明：对于均匀腐蚀，无论试样施加应力与否，表面的硫化物膜对钢铁有一定的保护性；对于硫化物应力腐蚀破裂。
Influence of corrosion product (sulfide scale) on general corrosion and sulfide stress corrosion cracking (SSCC) of UNS G11180 steel in 5%NaCl solution containing H 2S were studied by potentiodynamic scanning technique, slow strain rate tensile test and X-ray analysis. It has been proved that sulfide scale has a resistance to general corrosion and no obvious protection from SSCC.
