摘要： The invention provides a method of producing an oxidation-resistant metallic part which exhibits oxidation resistance even in an oxidation atmosphere. The method includes the step of applying mechanical energy to a surface of a metallic part in the presence of particulates, and forming a protective coating in a surface of the metallic part. When the metallic part thus treated is exposed in a high temperature-oxidation atmosphere, the protective coating is oxidized to restrain the proceeding of the oxidation of the metallic part, that is the internally proceeding formation of TiO2, thus serving a remarkable improvement of the oxidation resistance.

摘要： Surface-treating metallic parts are produced by applying mechanical energy to the surface of a metallic part and to a substance on or near the surface of the metallic part. The substance is different from the metallic part in composition. The applying step forms a mechanically-alloyed layer from the metallic part and the substance in the surface of the metallic part. The surface-modified layer such as the mechanically-alloyed layer is a non-peeling alloyed layer having a composition or structure different from that of the metallic part. The method is effective in surface-treating light metal materials of which the surfaces are difficult to treat. For example, the method is applicable to soft Mg alloys and Al alloys to improve their surface hardness, and the thus-treated alloys are usable in slide parts which are required to have good wear resistance. It is also applicable to the improvement in the oxidation resistance of Ti alloy parts which are used at high temperatures, and to the improvement in the corrosion resistance of Mg alloys which are said to have poor corrosion resistance.
