| A composition and method for providing a wear-resistant and fuel-saving coating on metals, particularly metal surfaces within internal combustion engines. A source of ammonium ions, an alkali metal in an aqueous medium, and the coating metal to be applied to the surface are combined to produce an electrolyte solution comprising a complex ion mixture. The electrolyte solution can be used to deposit the coating metal on conductive substrates. The coating metal may comprise phosphorus, sulfur, carbon, bismuth, boron, silicon, and combinations thereof. The electrolyte solution can be dehydrated in a hydrocarbon medium, thus providing novel materials for use as lubricating oil additives and as fuel additives. These new surfaces may significantly reduce coefficient of friction, smooth the flame front, reduce corrosion, enhance fuel economy, and reduce hydrocarbon emissions when used in internal combustion engines. | ||||||

| Trichlorofluoromethane refrigeration systems use mineral oil to lubricate the compressor. We have found that the use of 1,1-dichloro-2,2,2-trifluoroethane and mineral oil results in the formation of 1-chloro-2,2,2-trifluoroethane; in the absence of mineral oil, the use of 1,1-dichloro-2,2,2-trifluoroethane does not result in the formation of 1-chloro-2,2,2-trifluoroethane. We have found an additive which substantially reduces the formation of 1-chloro-2,2,2-trifluoroethane. Thus, the present invention provides a composition comprising: (a) 1,1-dichloro-2,2,2-trifluoroethane, (b) hydrogen-contributing lubricant: and (c) a composition comprising: (i) at least one phenol and (ii) at least one aromatic or fluorinated alkyl epoxide wherein the composition (c) substantially reduces the decomposition of 1,1-dichloro-2,2,2-trifluoroethane. | ||||||
