Oxidation resistance performance is greatly improved, to make up for the lack of common polycrystalline diamond

If the diamond surface coated with a layer of metal, high-pressure sintering process at high temperature, diamond can be a metal or alloy infiltrates well, even with the coating of diamond-metal or an alloy element in a chemical reaction of carbide, the formation of chemical bond, such that synthesized samples heat resistance, oxidation  synthetic diamond powder  and other properties have been greatly improved, made ​​up of ordinary polycrystalline diamond deficiencies in these areas, so as to improve tool life and performance purposes.  synthetic diamond  has been applied in the tool, but most studies on the diamond coating is that the interface between the synthetic diamond material aspects of the research has been reported rarely.
