Abstract (en)
[origin: WO0003047A1] The invention relates to a hard metal or ceramet body with a hard material phase consisting of WC and/or at least one carbide, nitride, carbonitride and/or oxicarbonitride of at least one of the elements from group IVa, Va, or VIa of the periodic table and a binding metal phase consisting of Fe, Co and/or Ni, said binding metal phase making up 3 to 25 mass %. In particular, WC crystallites should protrude beyond the hard metal or ceramet surface of the body by 2 to 20 mu m in order to improve the adhesion of surface layers that are applied.
