摘要： 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 &mgr;m 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.

摘要： A process for sulfurizing treatment of ferrous articles comprises positioning an electrolysis crucible containing a molten-salt bath of potassium thiocyanate and sodium thiocyanate and a pretreatment crucible containing a molten-salt bath of substantially the same composition adjacent to each other, assembling a unitary body by setting a plurality of the articles on a conductive support member in electrical contact therewith and attaching a cathode material to the support member to be out of contact with the articles and electrically insulated from the support member, immersing the unitary body in the bath contained in the pretreatment crucible, maintaining this bath temperature at substantially a prescribe bath temperature during ensuing electrolysis to bring the temperature of the unitary body near the prescribed temperature, transferring the unitary body from the pretreatment crucible to the bath in the electrolysis crucible while maintaining its temperature, and treating the articles by electrolysis. The process provides treated articles of consistently excellent surface quality.
