摘要

PROBLEM TO BE SOLVED: To provide such an anticorrosive coat which can exhibit a sacrificial anticorrosive effect for a long period by suppressing the degradation in the anticorrosive effect due to the sacrificial elution of a sacrificial anode metal in the dark.;SOLUTION: The anticorrosive coat 2 for the metal 1 used in the dark characterized by being formed of raw materials containing a sacrificial anode metal and semiconductive oxide particulates is provided. The anticorrosive coat 2 can be formed by a coating application method and a plating method.;COPYRIGHT: (C)2007,JPO&INPIT
