(57) [Problem] To improve the abrasion resistance, which is a drawback of aluminum, so that it can be used as a mechanical sliding part, a structural member of a machine, or a lightweight polishing tool. A viscous substance obtained by mixing an organic binder with fine aluminum powder is applied to the surface of aluminum, dried, and heated in a non-oxidizing or neutral atmosphere at a temperature in the range of 300 to 600 ° C. to form an organic binder. And the activated carbon is reacted with the aluminum fine powder to form a high hardness aluminum carbide coating on the aluminum surface. |
