Abstract (en)
A method for manufacturing an wear resistant component comprising the steps: - providing a capsule defining at least a portion of the final shape of the component; - providing a powder mixture comprising tungsten carbide particles and particles of a nickel-based or a cobalt based alloy: - filling at least a portion of said form with said powder mixture; - 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 or the chromium based alloy bond metallurgical to each other: characterized in that the tungsten carbide particles have a size of ‰¥ 250 µm and that the mean size of the nickel based or chromium based alloy is ‰¤ 1/5 of the size of the tungsten carbide particles.
