Methods of preparing cemented metal carbide substrates for deposition of adherent diamond coatings and products made therefrom

摘要

Methods for producing an adherent diamond film on a cemented metal carbide substrate are disclosed. Particularly, the present invention discloses methods of preparing the surface of a cemented metal carbide surface such that an adherent polycrystalline diamond coating may be deposited thereon using CVD techniques. Cutting tool inserts produced from such adherent diamond film coated cemented metal carbide articles are also disclosed.
