ABSTRACT:
A coating of refactory metals alloy, e.g. an alloy of tantalum and tungsten, is deposited on a substrate, such as the bore of a gun barrel, by reacting an alloy of the refractory metals with chlorine to form a mixture of the vapors of the refractory metal chlorides and reacting the resulting mixture of vapors with hydrogen to reduce the metal chlorides to the free metals. The alloy coating thus deposited possesses a finer grain structure and is more homogeneous and ductile than one obtained by chlorinating the tantalum and tungsten metals separately.
