In one aspect, a method for manufacturing a part for a centrifugal slurry pump is provided, comprising: forming a skeleton of the part having an outer dimension smaller than the part; placing the skeleton of the part in a metal enclosure having an interior dimension larger than the outer dimension of the skeleton of the part and thereby forming a space; adding a metal matrix composite powder into the metal enclosure to fill the space; and subjecting the metal enclosure to hot isostatic pressing, thereby allowing bonding of the metal matrix composite to the skeleton of the part to form the part.
