PURPOSE:To obtain a corrosion-proof body made of a metal having a smooth surface and excellent in corrosion-proof effect, by a method wherein a metal is applied to the surface of a substrate by flame spraying to form a porous metal layer and the whole is subjected to rolling processing to perform pore sealing. CONSTITUTION:Recessed and protruded parts are formed to the surface of a metal substrate 1 to roughen the same. On this roughened surface, a metal comprising Zn, Al, Cu, brass or a proper alloy is applied in a particulate form by flame spraying to form a porous metal layer 2. The surface of the metal layer 2 is subjected to rolling processing to be smoothed and to perform pore sealing finish. By this method, a corrosion-proof body reduced in the generation of a local battery with respect to the substrate 1 of the metal layer 2 and excellent in electric corrosion-proofness is obtained. |
