<p>A method for casting wear resistant parts which is capable of forming a hardened layer at a desired position with ease, whereby a wear resistant part can be obtained which has both wear resistance and toughness. To this end, the method comprises the steps of filling the inside of a holding member (16) which can be molten into molten steel with a hardened layer forming member (19) comprising superhard particles (17), setting the holding member (16) so filled with the hardened layer forming member (19) in a casting mold (10), and injecting molten steel into the casing mold (10), thereby causing not only the holding member (16) to be molten into molten steel but also the superhard particles (17) to be dispersed for solidification of molten steel. In addition, the hardened layer forming member (19) may be constituted by superhard particles (17), graphite powder (18) and/or metallic powder.</p> |
