METHOD FOR MANUFACTURE OF A HIP CONSOLIDATED COMPONENT AND A HIP:ED COMPONENT COMPRISING A WEAR RESISTANT LAYER |
摘要 |
A method for manufacturing of a wear resistant component including the steps of providing a form defining at least a portion of the shape of the component; providing 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 the form with the powder mixture; and subjecting the form to Hot Isostatic Pressing at a predetermined temperature, a predetermined isostatic pressure and a for a predetermined time so that the particles of the nickel-based alloy bond metallurgically to each other. |

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 a for a predetermined time so that the particles of the nickel-based alloy bond metallurgical metallurgically to each other. |
