CORROSION-RESISTANT FILM, EQUIPMENT FOR SEAWATER, AND CORROSION-RESISTANT FILM DEPOSITION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a film capable of maintaining the avoidance effect on marine organisms for a long time and enhancing corrosion resistance of a base material for seawater, and a method for depositing the film. SOLUTION: A corrosion-resistant film 62 is formed of a porous film of metal mainly consisting of corrosion-resistant metal against seawater and containing at least one kind of 0.0005-1.0 wt.% Ag and 3-5 wt.% Cu. The porous film is formed of metal particles 63 of the grain size of 10-100μm, and can maintain the avoidance effect for a long time because at least one kind of Ag and Cu determines the porosity based on the elution speed of≥1μg/cm2/day and the duration time of the speed.
