PROBLEM TO BE SOLVED: To provide an abrasion resistant composite wherein a high-hardness reforming surface layer without peel or crack is formed on its mold, as well as its manufacturing method. SOLUTION: In the abrasion resistant composite, an abrasion resistant reforming surface layer composed of rigid grains is monolithically molded on the mold face, via an interlayer formed by vitrification of a welding back layer comprising metal grains integrally molded on back side of the surface layer with the mold surface part in molding. Additionally, a double structured preform comprising both the abrasion resistant reforming surface layer formed by hardening of rigid grains and the welding back layer formed by hardening of metal grains is shaped. This preform is directly contacted against the reforming-needed area in the mold to be set, and the molten metal is cast into the mold for integrating the abrasion resistant reforming surface layer with the mold face via the interlayer formed by vitrification of the welding back layer.
