13Cr系列马氏体不锈钢的点蚀性能评价
Evaluation of Pitting Corrosion Performance of 13Cr Series Martensitic Stainless Steels
摘 要
采用动电位扫描、FeCl3溶液浸泡和模拟油井井下环境的CO2腐蚀试验等方法研究了四种不同成分的13Cr马氏体不锈钢的点蚀性能。结果表明, 动电位扫描和模拟井况腐蚀试验结果一致, 随耐点蚀当量指数(PRE)的增大, 材料的耐点蚀性能提高; 在FeCl3溶液中, PRE较低的材料发生均匀腐蚀,而PRE较高的材料发生点蚀。

Abstract
Pitting corrosion performance of four different 13Cr martensitic stainless steels were evaluated through the dynamic potential scanning method, FeCl3 solution immersion test and simulated downhole environment corrosion test. The results of dynamic potential scanning were agreement with those of the simulated corrosion. The pitting corrosion resistance increased with the increase of PRE, however, in the FeCl3 solution only general corrosion occurred for the lower PRE 13Cr materials while severe pitting appeared for the higher PRE 13Cr materials.
