Composite article with adherent CVD diamond coating and method of making |
摘要 |
A process for coating a tungsten carbide base material substrate with CVD diamond film includes carburization and gas-assisted vaporization of cobalt from the surface with simultaneous recrystallization of surface grains of tungsten carbide to change their stoichiometry for improved adherence. Also disclosed is a WC-Co cutting tool having a relatively fine WC grain size and being coated with adherent CVD diamond.
