Sulfide layers were made on the surface of AISI 1045 and SAE 52100 steels by means of low temperature ion sulphurization process. The tribological properties of the sulfide layers were investigated on an SRV reciprocating tester under dry and paraffin oil lubricated conditions. SEM equipped with EDAX and XRD were adopted to analyze the morphology and structure of the sulfide layers. The morphologies and composition of the wear scars were also analyzed.

采用低温离子渗硫技术在45＃钢和GCr15 钢表面形成渗硫层，用SRV 往复摩擦磨损试验机分别在干摩擦和液体石蜡润滑下对渗硫层的摩擦学性能进行了研究，用SEM、EDAX 和XRD研究了渗硫层的形貌和结构，并对磨痕的形貌及成分进行了分析。
