| 摘要 |
The invention relates to a wearing part consisting of a diamantiferous composite material and to a method for producing the same. The wearing part consists of a diamantiferous composite material comprising 40 to 90 % by volume of diamond grains, 0.001 to 12 % by volume of a carbide phase, constituted by one or more elements from the group including Si, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, B, Sc, Y, lanthanides and 7 to 49 % by volume of a metallic or intermetallic alloy having a liquidus temperature < 1400 DEG C. The metallic or intermetallic alloy contains the carbide-forming element(s) in dissolved or precipitated form and has a roughness at room temperature > 250 HV. |
