Claim:
1. A method for manufacturing of a wear resistant component comprising the steps: providing a form defining at least a portion of the shape of the component; providing a first powder, wherein said first powder is a powder mixture comprising 30-70 vol % of a powder of tungsten carbide and 70-30 vol % of a powder of a nickel based alloy, wherein the nickel based alloy consists of, in weight %: C: 0-1.0; Cr: 0-14.0; Si: 2.5-4.5; B: 1.25-3.0; Fe: 1.0-4.5; the balance being Ni and unavoidable impurities; and wherein the powder of tungsten carbide has a particle size of 105-250 μm and the powder of the nickel based alloy has a maximum particle size of 32 μm; filling at least a portion of said form with said first powder mixture; and subjecting said form to Hot Isostatic Pressing (HIP) at a predetermined temperature, a predetermined isostatic pressure and for a predetermined time so that the particles of the nickel-based alloy bond metallurgically to each other.
