Metal carbonitride coatings are deposited on assemblies, the parts of which are connected by an adherent material by first heating a selected assembly, including the adherent material, and subsequently contacting the assembly with a gaseous stream which will yield reactive hydrogen, nitrogen, carbon, and a selected metal, upon contact with the heated assembly. The gaseous stream may, for example, contain hydrogen, nitrogen, titanium tetrachloride, and a carbon-containing compound such as methane, or the hydrogen may be present in compound form, as in the system dimethylhydrazine, nitrogen, and titanium tetrachloride. Alternatively, the necessary reactive constituents for forming the metal carbonitride coating may be contained in a single compound, such as tetrakis (dimethylamino) titanium. |
