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。 The 45 steel and 2Cr13 stainless steel infiltration of sulfur surface wear test found that the 45 steel infiltration of sulfur layer wear marks a lot of corrosion peeling off the pit, but the stainless steel infiltration of sulfur coating wear scar did not occur. The mechanism of the weak corrosion of the sulphide layer was analyzed by using advanced equipment such as AFM, SEM and XPS. The results show that the sulphide layer with weak causticity is formed by the frictional heat, Corrosion damage is caused by corrosion behavior of 45 steel, which is protected from corrosion by its good corrosion resistance.
