GROWTH OF CVD DIAMOND ON Ta COVERED WC-6Co SUBSTRATE

摘要

Diamond thin films were deposited by hot filament CVD method on WC-6% Co substrate which were preheated by direct radiation from Ta filament at pure hydrogen atmosphere. X-ray diffraction and SEM were carried out to character the surface structure and morphology. Ta evaporated on the WC-6%Co surface is -beneficial to enhance both diamond quality and the adhesion.
