Abstract

We applied the auto hot deformation compensation of straight filament of close arrangement in grid form to synthesize CVD diamond films, and studied systematically the substrates made of ten strong carbides forming elements. We also stepped further to study the WC-Co substrates. The electron diffraction structure analysis showed that carbides grew first on strong carbides forming element substrates. During the nucleation process, we employed the atomic H to extract the carbon in WC on the surface so as to link C in WC to the H atom. The adhesion between the diamond film and the substrate was tested to be quite satisfactory.
