PURPOSE:To obtain a corrosion-resistance metallic material with superior corrosion resistance at high temp. by applying a soln. of an alkoxide of a specified metal such as Ti to the surface of a metal and by baking the soln. to form an amorphous thin metallic oxide film. CONSTITUTION:Alkoxides of one or more among Ti, Si, Ta and Al are dissolved is alcohol or the like, and the soln. is adjusted to the required concn. and viscosity. The adjusted soln. is applied to the surface of a metal such as iron, Cr or Ni or an alloy thereof, and it is baked at about 100-600 deg.C to form an amorphous thin film. The preferred thickness of the thin film is about 100- 5,000Angstrom .
