ABSTRACT:
A method of depositing a hard, fine grained metal or semi-metal alloy is described wherein a volatile halide of the metal or semi-metal is partially reduced and then deposited as a liquid phase intermediate compound onto a substrate in the presence of an alloying gas. The liquid phase deposited on the substrate is then thermochemically reacted to produce the hard, fine grained alloy. Also described are products which may be produced by the above method.
