ABSTRACT:
A process and apparatus for producing a diamond film from a gas phase, in which a fuel gas is burnt by oxygen gas in a torch, to thereby provide a gas flame jet having a high temperature and high speed sufficient to form a high quality diamond film on a substrate, by an unlimited use of various kinds of combustible carbon compound gases as the fuel gas. A process and apparatus for producing a diamond film from a gas phase, in which a thermal spray material is fed to a combustion flame to thereby form an intermediate layer of a mixture of the thermal spray material and diamond between a substrate and a diamond film, to thereby provide a high purity diamond film having an improved adhesion to the substrate.
