Abstract
Sulfide layers were made on the surface of AISI 1045 and SAE 52100 steel by low temperature ion sulphurization. The tribological properties of these layers were investigated on an SRV reciprocating tester. SEM equipped with EDAX and XRD were adopted to analyze the morphology and structure of these layers. The morphology and composition of the wear scars were also analyzed. The results show that these layers were porous and composed of FeS, FeS2 and substrate phases. Under both dry and paraffin oil lubricated conditions, these layers show remarkable friction-reducing effects and improved wear resistance. With the increase of the layer thickness, its antiwear life is prolonged, but the thickness and substrate de not affect the friction coefficient greatly. Under the same experimental conditions, the antiwear life of these layers on SAE 52100 steel is longer than that on AISI 1045 steel, and the wear resistance of the former is better.
