A process for working metal comprising contacting a metal workpiece with a metal working tool and a water soluble metal working fluid, said tool having an antiwear coating disposed thereon which includes at least one of a metal nitride and a metal carbonitride, and said metal working fluid includes:

A process for working metal comprising contacting a metal workpiece with a metal working tool and a water soluble metal working fluid, said tool having an antiwear coating disposed thereon which includes at least one of a metal nitride and a metal carbonitride, and said metal working fluid includes: (a) a first amine generally described by the formula: [Figure] wherein: R1 is selected from the group consisting of hydrogen, hydrocarbyl moieties, alkoxy moieties and polyalkoxy moieties; R2 is selected from the group consisting of C7 to about C20 hydrocarbyl moieties; R3 is selected from the group consisting of alkoxy moieties and polyalkoxy moieties; (b) a second amine described by the formula: [Figure] wherein: R4 is selected from the group consisting of (i) hydrogen, (ii) C1-C6 hydrocarbyl moieties and (iii) monomeric and polymeric alkoxy moieties consisting essentially of alkoxy units selected from the group consisting of ethoxy, 2-propoxy, 2-butoxy and mixtures thereof; R5 is selected from the group consisting of (i) C1-C6 hydrocarbyl moieties and (ii) monomeric and polymeric alkoxy moieties consisting essentially of alkoxy units selected from the group consisting of ethoxy, 2-propoxy, 2-butoxy and mixtures thereof; R6 is selected from the group consisting of (i) monomeric and polymeric alkoxy moieties consisting essentially of alkoxy units selected from the group consisting of ethoxy, 2-propoxy, 2-butoxy and mixtures thereof; such that said second amine contains a total of 6 or fewer alkoxy units; (c) an acid-derived compound selected from the group consisting of organic acids, inorganic acids, and salts thereof; wherein the ratio by weight of the second amine to the first amine is about 20:1 to about 0.05:1 and the ratio by weight of the acid-derived compound to the first amine is about 3:1 to about 0.01:1.
