That is, in the conventional method, an alloy layer having only one property selected from wear resistance, heat resistance, corrosion resistance, etc. is formed over the entire surface of the casting. In contrast, in the present invention, a linear additive material that penetrates the mold wall and reaches the cavity is inserted from the outside of the mold, and an alloy layer is formed at a desired location on the surface of the casting. Accordingly, it is possible to manufacture a casting having different properties at a plurality of desired locations on the surface of the casting.
