A sliding member having excellent seizure resistance comprising a metallic member provided with a sulfide-based solid lubricating layer on the sliding surface thereof is provided, characterized in that the interface of the metallic member in contact with said solid lubricating layer is provided with a surface roughness Rmax of 1 μm or higher. The sliding member above is obtained by preparing an aqueous solution dissolved therein one or two types or more of thiocyanates or thiosulfates of alkali metals or alkaline earth metals, and by performing electrolytic treatment in which a steel member the surface roughness thereof is controlled is used as the anode. In this manner, an iron sulfide based layer is formed on the surface of the steel member by using the Fe component derived from the steel and the S component from the solution as the reacting agents.
A sliding member having excellent seizure resistance comprising a metallic member provided with a sulfide-based solid lubricating layer on the sliding surface thereof, characterized in that the interface of the metallic member in contact with said solid lubricating layer is provided with a surface roughness Rmax of 1 μm or higher.
A sliding member having excellent seizure resistance comprising a steel member provided with an iron sulfide-based, a molybdenum sulfide-based, or a tungsten sulfide-based solid lubricating layer on the sliding surface thereof, characterized in that the interface of the steel member in contact with said solid lubricating layer is provided with a surface roughness Rmax of 1 μm or higher.
