Abstract

In a process for producing a titanium boride coating on an article having a melting point over 780 DEG C. and containing at least at its surface a metal capable of forming borides or a carbide or nitride thereof, the surface to be coated is first subjected to an atmosphere containing hydrogen and a boron halide at a temperature between 600 DEG C. and 1200 DEG C. to form a boride diffusion layer and is then subjected to an atmosphere containing hydrogen, a boron halide and a titanium halide at a temperature between 780 DEG C. and 1000 DEG C. until a titanium boride coating at least 2m thick is formed over the diffusion layer, neither operation being performed at a temperature above the melting point of the article. Coating may be effected in three ways, viz. (a) the article may be subjected to an atmosphere containing only hydrogen and boron halide at a temperature of 600 DEG C.-780 DEG C. to form the diffusion layer and the temperature then raised above 780 DEG C. and titanium halide added to the atmosphere to deposit titanium boride, (b) the article may be subjected to an atmosphere containing only hydrogen and boron halide at a temperature above 780 DEG C. to form the diffusion layer and titanium halide then added to the atmosphere to deposit titanium boride at the same temperature, and (c) the article may be subjected to an atmosphere containing hydrogen, boron halide and titanium halide at a temperature of 600 DEG -780 DEG C. to form the diffusion layer and the temperature then raised above 780 DEG C. to deposit titanium boride. Specified halides are BCl3 and TiCl4 and the reaction gas mixtures may be diluted with an inert carrier gas, e.g. argon or nitrogen. Coatings may be formed on surfaces of iron group metals and alloys, particularly steels containing at least 1% of at least one of V, Cr, Mo and W, and on surfaces of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W, or nitrides or carbides of these metals. After coating, steels may be quenched to room temperature. The coating of the following articles is disclosed:- steel thread-guide rollers, steel mandrels for tube drawing, wire-drawing dies made of a steel consisting of C 1.2%, W 8%, Mo 5%, Cr 4%, V 2.5%, Co 12%, remainder Fe, molybdenum evaporator boats and feeler needles, and cold-shaping tools made of WC-Co hard metal.
