- 19 - Abstract of the Disclosure 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.
