An inert-gas curtain method, in which a combustion flame of oxygen/acetylene mixture is protected from the air by a surrounding inert-gas flow, has been developed for the deposition of microcrystalline diamond films. As a result, highly uniform and highly dense microcrystal films of diamonds possessing the quality of natural diamond were successfully prepared. The inert-gas flow allows the hydrocarbon radicals in the flame to be varied for preferential deposition of diamonds.
