Method for lubricating metal-metal contact systems in metalworking operations with cyclohexyl esters

摘要

Metal-metal surface contact systems in metalworking processes may be lubricated by applying thereto a composition comprising an ester, wherein the ester has a full film traction coefficient of less than about 0.05 at a pressure of about 0.5 to about 1.2 GPa, a temperature of about 50 DEG C. and a sliding velocity of about 0.5 to about 10 msec-1. The ester is represented by the general formula: e set forth in the Summary of the Invention. The composition may be mixed with a solvent to form a solution or emulsified prior to application to the metallic surface.
