Description
Summary:The effect of shot-peening treatment with the particulate MoS 2 solid lubricant on the wear resistance of steel in the dry rolling/sliding contact wear tests was investigated. The duplex shot-peening treatment with ceramic balls and the particulate MoS 2 solid lubricant provided excellent wear resistance under a severe loading and sliding condition because the uniform and minute surface roughness given by shot-peening treatment with ceramic balls could keep shot-peened MoS 2 particles with a low friction coefficient on the sample surface. Furthermore, the sample surface was covered with shot-peened MoS 2 particles by a MoS 2 layer formed during the rolling/sliding contact wear test.
