摘要： 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.

摘要： The invention concerns a multipurpose lubricant comprising at least a phosphoric ester (A) of general formula (I) wherein: k = 2 or 3; m is a number from 0 to 8; x = 1 or 2 and R represents a linear alkyl or alkenyl radical with 10 to 20 carbon atoms or a salt of such an ester, and at least a polysulphide (B) of general formula: R'-Sy-R' wherein y is a number ranging from 2 to 8 and R' represents a tertio-alkyl radical with 4 to 18 carbon atoms, the volume ratio ranging between 0.01/1 to 1/1.
