AQUEOUS LUBRICANT FOR PLASTIC WORKING OF METALLIC MATERIAL, HAVING HARDLY CRYSTALLIZABLE PROPERTY, AND EXCELLENT IN HYGROSCOPIC RESISTANCE, CORROSION RESISTANCE AND WORKABILITY, AND METALLIC MATERIAL HAVING LUBRICATING FILM THEREOF FORMED THEREON

摘要

PROBLEM TO BE SOLVED: To provide an aqueous lubricant for plastic working of a metallic material, capable of forming a lubricating film having the hardly crystallizable property, and excellent in the hygroscopic resistance, the corrosion resistance and the plastic workability.;SOLUTION: The aqueous lubricant for plastic working of a metallic material contains alkaline metal borate salts (A), wherein the alkaline metal borate salts (A) contain lithium borate; the molar ratio of lithium to all the alkaline metals in the alkaline metal borate salts (A) is 0.1 to 1.0; and the molar ratio (B/M) of boron (B) to alkaline metals M in the alkaline metal borate salts (A) is 1.5 to 4.0.;COPYRIGHT: (C)2012,JPO&INPIT
