Title:
METHOD FOR WORKING OR FORMING METALS IN THE PRESENCE OF AQUEOUS LUBRICANTS BASED ON METHANESULPHONIC ACID
Document Type and Number:
WIPO Patent Application WO2003042342
Kind Code:
A3
Abstract:
The invention concerns a method for working or forming metals which consists in using an aqueous lubricant containing as water-soluble extreme pressure additive, methanesulphonic acid or a water-soluble methanesulphonic acid salt. The water-soluble methanesulphonic acid salt is an alkali or alkaline-earth, ammonium, alkanolamine or ethoxylated fatty amine salt. The inventive aqueous lubricants have good extreme pressure properties and good properties with respect to corrosion.
