Abstract
Abstract A METHOD OF FORMING A TITANIUM CARBIDE MATRIX HAVING A DUCTILE METAL DISPERSED THEREIN BY CHEMICAL VAPOR DEPOSITION OF TITANIUM CARBIDE FROM HYDROGEN REDUCTION OF A TITANIUM HALIDE AND A CARBON HALIDE AT ELEVATED TEMPERATURES. THE DUCTILE METAL IS GENERATED WITHIN THE REACTOR AS A HALIDE AND TRANSPORTED TO THE DEPOSITION SITE BY AN INERT GAS CARRIER, WHERE THE ELEMENTAL TITANIUM, CARBON, AND DUCTILE METAL REACT TO FORM A DEPOSIT OF TITANIUM CARBIDE CONTAINING THE DUCTILE METAL. THE DUCTILE METAL HALIDE VAPOR IS INITIALLY SEPARATED FROM THE TITANIUM HALIDE AND CARBON HALIDE VAPOR STREAM TO PREVENT PREMATURE REDUCTION OF THE DUCTILE METAL CHLORIDE.
