Title:
METALLIC MATERIAL FOR PLASTIC WORKING WITH GRADIENT TWO-LAYER LUBRICANT COATING FILM AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2002/072345
Kind Code:
A1
Abstract:
A metallic material for plastic working which has excellent lubricating properties. The metallic material for plastic working has a gradient two-layer lubricant layer which comprises a base layer located on the metal side, having a thickness of 0.1 to 15.0 $g(m)m, and comprising an inorganic compound as the main component and a lubricant layer located on the surface side, having a thickness of 0.1 to 10.0 $g(m)m, and comprising a lubricant as the main component and in which the ratio of the thickness of the lubricant layer to that of the base layer is from 0.2 to 3.0. The inorganic compound is preferably a phosphate, sulfate, borate, silicate, molybdate, tungstate, etc. The lubricant is preferably a metal soap, wax, polytetrafluoroethylene, molybdenum disulfide, graphite, etc. The metallic material may be iron, steel, stainless steel, etc. The gradient two-layer lubricant layer can be formed by bringing the surface of a metallic material into contact with a water-based treating liquid containing an inorganic compound and a lubricant as major ingredients and then drying the surface.
