摘　　要：概述了金属在湿H2 S环境中的腐蚀破坏类型、腐蚀机理、实验研究方法和影响因素 ,探讨了湿H2 S的定义 ,提出 :在区分溶液H2 S和薄液H2 S腐蚀的基础上 ,加强湿H2 S环境下腐蚀机理、高温高压湿H2 S条件下的腐蚀开裂行为和机理、阳极溶解和HIC的相互关系的研究 ;发展和规范湿H2 S环境下设备腐蚀破坏的检测方法和相关的工业标准 ,开展H2 S环境下寿命预测和安全评估技术工作 ;完善室内模拟湿H2 S环境下腐蚀实验技术 .The types,mechanisms,research methods and influence factors of corrosion and cracking of metals in wet hydrogen sulfide were summarized in the paper. The definition of wet hydrogen sulfide was also discussed.Further researches were proposed as follows:understanding corrosion mechanisms in wet hydrogen sulfide,corrosion and cracking in high temperature and high pressure hydrogen sulfide and the relations between anodic SCC and HIC;developing methods for detecting H_2S induced corrosion damage of facilities in wet hydrogen sulfide and the relevant industrial standards;carrying out works on lifetime prediction and safety evaluation and establishing test techniques to simulate sulfide hydrogen corrosion indoor.
