A method for manufacturing a wear resistant component, includes the steps of: providing a mould defining at least a portion of the component; providing a powder mixture comprising a first powder of tungsten carbide and a second powder of a cobalt-based alloy, wherein the powder mixture comprises 30-70 vol % of the first powder of tungsten carbide and 70-30 vol % of the second powder of the cobalt-based alloy and the second powder of cobalt-based alloy comprises 20-35 wt % Cr, 0-20 wt % W, 0-15 wt % Mo, 0-10 wt % Fe, 0.05-4 wt % C and balance Co, wherein the amounts of W and Mo fulfills the requirement 4<W+Mo<20; filling the mould with the powder mixture; and subjecting the mould to Hot Isostatic Pressing (HIP) at a predetermined temperature, a predetermined isostatic pressure and for a predetermined time so that the particles of the powder mixture bond metallurgically to each other. |
