ABSTRACT:
Compositions, and the process of their use, for extending the useful life of machine elements wherein two metal bearing surfaces are in contact one with the other, or with a working surface, e.g., drill bits, gear faces, bearings, sleeves, bushings, ball-joints, journalled shafts, and the like. The compositions are formed by use of a carrier, e.g., as an oil, grease, synthetic, or the like, by the addition thereto of reactants comprised of an electron donor metal, or compound, and a decomposable plating-metal bearing compound, one or both of which reactants is encapsulated or coated to separate the reactants. In the process embodiment which embodies use of the composition at preselected conditions which characterize those exhibited at the metal bearing surfaces of the machine elements during an operating function, the encapsulating material is broken down, this causing release, and contact, of the reactants to produce a chemical reaction wherein the plating-metal portion of the decomposable plating-metal bearing compounds is electrodeposited, or electroplated, upon the metallic bearing surfaces of the machine element, this extending its wear capabilities, and useful life. A particularly preferred process is one wherein the reactants are added to a drilling mud to form compositions used in drilling for oil or gas, which results in the release and chemical reaction of the reactants at the bottom of a well bore, this electroplating the plating-metal upon the drill bit to extend its useful life.
