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.
