摘要： A composite metallizing wire useful in thermal flame spraying, having a conductive metallic solid core wire strand and a coating consisting of solid lubricant particles (i.e., graphite, BN, Teflon) and wear-resistant particles (i.e., SiC, TiC, Cr3C2) homogeneously suspended in a conductive metal (i.e., Ni, Fe, Cr, Mo, Ti) complementary to said solid core wire strand. A method of making such composite metallizing wire useful in thermal flame spraying, comprising submersing a solid core wire mandrel of conductive metal in a plating bath to act as a cathode, the bath containing conductive metal salt and an electrolyte having a salt with a depositable metal and a dispersant of wear-resistant particles (i.e., in an amount of from 20-150 grams/liter) and solid lubricant particles (i.e., in an amount of from 10-200 grams/liter), and energizing the electrolyte to codeposit metal from said electrolyte along with wear-resistant particles and solid lubricant particles onto said-wire mandrel. A method of thermal spraying to produce a metal matrix composite coating, comprising providing a thermalizing through-flow chamber with an exit nozzle, the chamber having a gas flow-through of at least 100 ms-1, establishing a flame in said chamber, and feeding a composite coated wire into said flame to be melted and projected by the gas flow to a target, the wire being constructed as above.

摘要： A method of thermally spraying a solid lubricant (i.e. graphite or BN) impregnated metal matrix onto a metal target, using the steps of: (a) creating a flame or arc into which a consummable strand is fed, the strand being constituted as a hollow sheath of metal and a core therein comprising essentially solid lubricant powder particles, the flame or arc melting the metal of such strand; (b) applying a pressurized jet of atomizing gas to the melt and included graphite particles to project a spray of molten heavy metal and graphite particles generally homogeneously distributed throughout such spray, said graphite being protected against ablation during transit from the flame or arc to the target; and (c) surface heat treating essentially only the deposit to precipitate additional graphite while densifying the metal and controlling microstructure.

摘要： Method of depositing an Fe x O comprising coating onto a light metal substrate by use of wire-arc thermal spraying that propels atomized drouplets by use of atomizing gases, comprising: preparing at least one surface of the light metal substrate to present an exposed essentially non-oxidized substrate surface; and thermally spraying melted droplets of a steel feedstock wire onto the prepared surface by use of propellant gases to deposit a composite coating, the gases being controlled as to content to regulate the exposure of the droplets to oxygen so that Fe x O is substantially the only iron oxide formed during spraying, x being.5-1.5.

摘要： Method of making a composite coated article by the steps of: (a) initiating chemical vapor deposition of separated diamond or diamond-like particles onto a nondiamond or nondiamond-like substrate surface by use of low pressure metastable deposition of carbon in the presence of atomic hydrogen and at a temperature the 600-950.degree.C) that favors the nucleation of such particles, the substrate being selected to retain its strength related properties after said chemical vapor deposition (i.e., SiAlON, Si3N4, SiC, Si, Ti, Co cemented WC, TiC, Ni-Mo cemented TiCN); (b) substantially suppressing nucleation of additional particles (heating to above about 1000.degree.C) before formation of a contiguous film of said particles while permitting the existing particles to grow to a predetermined maximum crystal size consistent with separated crystals; and (c) depositing a mechanically tough, diamond and substrate-wetting metal binding material (i.e., Ti, Ni, Co, Mn, Cr, Mo, Fe) onto and across said separated particles and exposed substrate surface to form the composite coated article. Chemical vapor deposition comprises thermal decomposition (i.e., microwave plasma, discharge, filament heating) of a hydrocarbon gas containing hydrogen, with or without diamond seeding. The binding material preferably contains a brazing agent (i.e., Cu, Ag, Sn).

摘要： A method of making and the resulting product for a disk brake rotor with a self-lubricating, thermally conductive coating thereon that enhances the friction wear life of a disk brake assembly within which it is used, comprising: (a) controllably roughening at least the outside braking surfaces of a lightweight metal disk brake rotor, said roughening being carried out to promote mechanical adhesion of coatings applied thereover; (b) thermally spraying one or more coatings onto said roughened outside braking surface, the exposed coating being electric arc sprayed using a codeposit of iron-based material and powdered graphite to form an iron matrix composite coating; and (c) surface heat treating essentially said exposed coating to dissolve and precipitate graphite and form a simulated cast iron and also to densify the coating and remove residual stresses resulting from deposition. To inhibit heat transfer, the method may further comprise forming the lightweight metal rotor to have a pair of annular ring walls supported by a hub, the ring walls being separated by a plurality of vanes for inducing air cooling as the rotor rotates, and interposing a thermally sprayed metallic-based heat barrier coating between said rotor and exposed coating. The barrier coating may be comprised of a nickel-based material which preferably includes graphite codeposited therewith. The cooling vanes and intermediate coating cooperate to protect the rotor against extreme heated conditions. 6829L
