摘　　要：对45钢和2Cr13不锈钢的渗硫表面进行磨损试验后发现，45钢渗硫层磨痕处产生了大量腐蚀剥落坑，而不锈钢渗硫层磨痕却未产生。利用AFM、SEM、XPS等先进设备分析了渗硫层弱腐蚀现象的产生机理，结果表明：摩擦过程中，由于摩擦热的作用，渗硫层生成了具有弱腐蚀性的硫酸根，对没有耐蚀性能的45钢造成了腐蚀破坏，而不锈钢以其良好的耐蚀性免受腐蚀破坏。After the friction and wear test carried out on the FeS surface on the ＂45＂ steel and 2Cr13 steel, it can be found that the micro-corrosion phenomenon occurs on the worn scars of ＂45＂ steel, but not on the 2Cr13 steel. The advanced equipment, such as AFM, SEM ＋ EDS and XPS are employed to analyze the mechanism about the micro-corrosion of FeS coating. The results show that in the course of friction, under the frictional heat, the sulfate radical with mild corrosion is produced, so that the＂45＂ steel without any anti-corrosion performance is corroded in some certain, meanwhile the 2Cr13 steel is not corroded because of its excellent corrosion resistance.
