摘要:

分别设计了金属-金属、金属-四氟乙烯、金属-橡胶、金属-塑料薄膜4种接触类型，探究不同类型接触面对不锈钢缝隙腐蚀的影响。对316L奥氏体不锈钢的缝隙构型进行FeCl₃浸泡实验和电化学实验，研究了其对缝隙腐蚀行为的影响，通过激光共聚焦显微镜对缝隙腐蚀后样品的宏观形貌进行了研究。结果表明，金属-金属接触面条件下腐蚀形貌宽度最大，深度最浅，蚀坑横向发展，蚀坑达到一定深度后，腐蚀溶液横向扩散更容易。金属-橡胶接触面下腐蚀形貌宽度最小，深度最大，蚀坑纵向发展，这与橡胶所受应力有关，始终紧贴样品表面，腐蚀溶液不易发生横向扩散。电化学测试表明，不同类型接触面缝隙试样的破钝化电位相对于无缝隙试样均有明显降低。

Abstract：

316 stainless steel pate was paired face by face with four plates of different materials respectively, i.e. 316SS, tetrafluoroethylene, rubber and plastic, and then the crevice corrosion behavior of the 316SS for the above four pairs was assessed via immersion test in FeCl₃ solution, while the relevant electrochemical performance was examined in an artificial seawater. After corrosion test, the samples were examined by laser confocal microscopy. Results show that among others, the pair 316SS/316SS presented the widest corrosion area with the most shallow depth, indicating that the corrosion pits tended to spread preferentially sideways. When the corrosion pits reach a certain depth, the lateral migration of corrosive solution got easier. The corrosion morphology of the pair 316SS/rubber showed the minimum width with the maximum depth, suggesting the longitudinal development of the corrosion pit, which is related to the stress applied on the rubber. In that case, the corrosive medium is closely attached to the steel surface, hence hard to migrate laterally into the gab, thereby the corrosion expanded vertically in depth. Furthermore, the relevant mechanisum of crevice corrosion for different type of pairings was analyzed through electrochemical measurements.

Key words： crevice corrosion stainless steel contact surface immersion
