Abstract (en)
[origin: WO2012035497A1] Powdered grit comprising a fused cermet of zirconium oxide (ZrO2) doped with a dopant chosen from yttrium, scandium, and a mixture of scandium and of aluminium and/or of cerium, and of nickel (Ni) and/or of cobalt (Co), said cermet having a eutectic structure, the contents, in mol%, of zirconium oxide, nickel and cobalt being such that 0.250Ni + 0.176Co = (ZrO2+ dopant) = 0.428Ni + 0.333Co, and said powdered grit having a median diameter D50 of between 0.3 µm and 100 µm.
