摘　　要：为提高铁路客车车体的防腐性能,研究3种常用客车车体钢材的耐腐蚀性能。采用周期浸润和全浸试验方法,开展耐腐蚀性能试验,并处理腐蚀产物。根据试验结果,比较3种钢材的耐腐蚀性能,从形貌和化学成分2方面分析钢材的腐蚀产物,研究其腐蚀机理,为选择车体钢材提供参考。In order to improve the corrosion resistance of railway passenger car body, the corrosion resistance of three kinds of steels commonly used for passenger car body was studied. Carry out corrosion resistance test by periodic immersion and total immersion test methods and treat corrosion products. According to the test results, the corrosion resistance of the three kinds of steels are compared, the corrosion products of the steels are analyzed from the aspects of morphology and chemical composition, and the corrosion mechanism is studied, so as to provide reference for the selection of steel for car body.
