  • Vapor deposition of metal compound coating utilizing metal sub-halides and coated metal article
    Patent number: 4803127
    Abstract: A process for the chemical vapor deposition on substrates of coatings comprising compounds of a titanium sub-group of metals, the vanadium sub-group of metals and the chromium sub-group of metals at temperatures in the range of 250.degree. C. is disclosed. Sub-halides, such as TiCl.sub.3, are reacted with N.sub.2 and H.sub.2 and thermodynamic and kinetic parameters are manipulated by flow rates and partial pressures of the reactants to achieve the deposition reaction in the temperature range of 250.degree. C. to 850.degree. C. The invention also relates to a metal compound coated article. An apparatus for performing the process is also disclosed.
