AQUEOUS LUBRICANT, METALLIC MATERIAL AND METAL WORKED PART

Japanese Patent JP2016216536

A

PROBLEM TO BE SOLVED: To provide an aqueous lubricant for metallic material plastic working capable of forming a lubricant film, e.g., excellent in lubricity under a high-humidity environment (moisture absorption resistance) and seizure resistance to high easiness metal working, and also excellent in long period chemical stability, a metallic material having a lubricant film formed by the aqueous lubricant on the surface, and a metal worked part obtained by molding the metallic material.SOLUTION: Provided is an aqueous lubricant for metallic material plastic working in which aliphatic polycarboxylic acid having the carbon number of 5 to 8 and a solubility to water at 20°C of 10 g/100 mL or more and an alkaline-earth metal compound are blended into water, or the alkaline-earth metal salt of the aliphatic polycarboxylic acid is dissolved or dispersed into water.SELECTED DRAWING: None
