LUBRICANT COMPOSITION FOR STEEL MATERIAL SUBJECTED TO THERMAL DIFFUSION TREATMENT WITH TIN OR TIN-ZINC, AND LUBRICATION USING THE SAME

摘要

PURPOSE:To provide a lubricant compsn. which imparts excellent load and abrasion resistances to a steel material subjected to a thermal diffusion treatment with tin or tin-zinc. CONSTITUTION:A lubricant compsn. comprises an organozinc compd. and optionally an ester sulfide. A part made using a steel material subjected to a thermal diffusion treatment with tin or tin-zinc is treated with the lubricant compsn.
