To provide an automobile component having excellent corrosion resistance and further having excellent productivity.SOLUTION: Provided is an automobile component 1 made of: a bolt fastening part 12 including an Fe-Zn-Al alloy in a surface layer 14; and a body part 10 made of cast iron and integrally molded with the bolt fastening part 12. Since the surface layer 14 includes an Fe-Zn compound, the Fe-Zn compound is present on the side of the surface (fastening face 12f) of the bolt fastening part 12. The automobile component 1 has excellent corrosion resistance by being provided with the surface layer 14 even if a part of the fastening face 12f is not covered on a bolt head. The automobile part 1 can be easily produced by simultaneously casting a stock plate including Zn and Al, e.g., upon casting the body part 10.SELECTED DRAWING: Figure 1
【課題】耐食性に優れ、製造性にも優れる自動車部品を提供する。【解決手段】自動車部品1は、表層14にFe−Zn−Al合金を含むボルト締結部12と、鋳鉄からなり、ボルト締結部12が一体に成形されてなる本体部10とを備える。表層14はFe−Zn化合物を含むため、ボルト締結部12の表面(締結面12f)側にFe−Zn化合物が存在する。自動車部品1は、締結面12fの一部がボルト頭部に覆われていなくても、表層14を備えることで耐食性に優れる。自動車部品1は、例えば本体部10を鋳造する際に、ZnとAlとを含む素材板を同時に鋳込むことで容易に製造できる。【選択図】図1
