ABSTRACT:
A method of using an electrochemical process in oil-based lubricants to form friction-reducing and wear-reducing iron phosphate films on metal surfaces. An electrolytic additive of dialkyl hydrogen phosphate is first added to the oil-based lubricant to improve its electrical conductance and to make it an ionic conductor. This method enables not only the formation of uniform iron phosphate films on metal surfaces but also the in-situ repair of such films after damage has occurred.
