ABSTRACT:
The invention provides pore-free, dense refractory metal binder composite and laminate coated articles including ceramic or cemented carbide substrates coated with refractory metal carbide, nitride, or carbonitride binder composite coatings. A tungsten carbide cobalt composite coated tungsten carbide cobalt article is provided. Refractory metal carbide, nitride and carbonitride binder composite layers and/or refractory metal carbide, nitride and carbonitride layers can be combined with binder layers to construct laminate coated articles. Among such laminate coated articles are structures which include at least one layer of tungsten carbide cobalt composite and at least one layer of cobalt on a tungsten carbide cobalt substrate.
