ABSTRACT:
A method of depositing a hard metal alloy is described wherein a volatile halide of titanium is reduced off the surface of a substrate and then reacted with a volatile halide of boron, carbon or silicon to effect the deposition on a substrate of an intermediate compound of titanium in a liquid phase. The liquid compound on the substrate is then reacted in the presence of hydrogen to produce a hard deposit containing titanium and boron, carbon or silicon. Also described are products which may be produced by the above method.
