Abstract

Métallurgie. Pièce en métal dur fritté composée d'au moins un carbure tel que le carbure de tungstène en plus d'une phase liante formée essentiellement de cobalt et/ou de nickel, la pièce en métal dur étant pourvue d'une zone superficielle borurée présentant une épaisseur de 1 à 100 microns et de préférence de 20 à 80 microns, caractérisée en ce que le métal dur contient de petites quantités de carbures additionnels cubiques tels que VC, TiC, TaC, Mo2 C, ZrC, NbC et/ou Cr 3 C2 , en ce que la proportion de la phase liante est de 6 à 40 %, et de préférence de 8 à 20 %, du volume de la pièce, et en ce que la grosseur de grain moyenne du carbure de tungstène est de 0,2 à 1,5 micron, et de préférence de 0,2 à 1 micron. Application : organes et pièces soumises à une forte usure dans des travaux de coupe.
