Abstract
A method of producing a ferrous alloy material having improved wear resistance comprising (1) mixing powders of a ferrous alloy, tungsten and optionally at least one element selected from the group consisting of C, Ni, Mn, Mo, Cr, and Cu, (2) sintering the mixture of powders of step (1) to form a sintered product, (3) infiltrating the sintered product of step (2) with molten copper or a copper alloy to produce an infiltrated sintered product and (4) cooling the infiltrated sintered product of step (3).
