ANTICORROSIVE COATING FOR METAL, ANTICORROSIVE COATED FILM, COMPLEX COATED FILM AND CORROSION-PREVENTING METHOD FOR METAL

摘要

PROBLEM TO BE SOLVED: To provide an anticorrosive coating capable of exhibiting rustproof function over a long period in an electrochemically corrosion-preventing method. SOLUTION: An anticorrosive coating for metals 1 comprises a sacrificial anode metal and a photocatalyst. An anticorrosive coated film 2 is formed by applying the anticorrosive coating onto the metal 1. Preferably, a complex coated film 4 is obtained by applying a topcoat onto the anticorrosive coated film 2 to form an inorganic porous film 3. COPYRIGHT: (C)2006,JPO&NCIPI
