摘要
Method for obtaining a protective layer of copper parts, adherent, resistant and with a high rate of covering of the substrate, by passivating anodization, characterized in that said copper parts are immersed in a bath of liquid KF, 2HF and subjected at an anodic current of low suficial density less than 0.1 A / dm2, the current may be continuous or intermittent.
