Abstract: A method of forming friction-reducing and wear-resistant silver/molybdenum coating material by co-depositing quantities of silver and molybdenum simultaneously forming nano-crystalline binary mixtures on iron surfaces.

Abstract: A method of using an electrochemical process in oil-based lubricants to form friction-reducing and wear-reducing molybdenum/iron phosphate films on cast iron surfaces. A cast iron surface acting as the anode means is first coated with a thin film of molybdenum and then bombarded with high energy inert gas ions to form a layer of molybdenum/iron alloy on the surface before the electrochemical process. An electrolytic additive of dialkyl hydrogen phosphate is 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 molybdenum/iron phosphate films on cast iron surfaces but also the in situ repair of such films after damage has occurred.
