摘要
采用金相显微镜和X射线衍射相结合的方法,观察与分析了高温盐浆泵用新型不锈钢的金相组织,并通过多种腐蚀试验方法,研究了不同热处理制度对钢的耐腐蚀性能的影响。试验结果表明,这种钢在1100℃经两小时水冷固溶处理后,碳化物基本全部固溶于奥氏体基体中,适量的铁素体呈块状或点状弥散均匀分布,具有良好的耐均匀腐蚀、晶间腐蚀、点蚀和电化学腐蚀性能。
The microstructure of a new type of stainless steel for high-temperature brine pumps is analyzed by means of the metallurgical microscope and X-ray diffraction spectrum. The influence of different heat treatment processes on the corrosion resistance of the steel is investigated by various methods of corrosion test. The test result shows that the steel possesses good uniform corrosion-, intergranular corrosion-, pitting corrosion- and electrochemical corrosion-resistant properties after water cooled solution heat treatment for two hours at 1100℃.
