Cemented carbides with a binder enriched surface are made by adding a metal, hydride, nitride or carbonitride of a Group IVB or VB transition metal (Ta, Nb, Ti, Hf, Zr, V) into the powder mixture prior to sintering. The binder enriched surface may be coated with a refractory oxide, nitride, boride a...
