Postplating treatment does not commonly used in the chromium plate, because of passivity and tarnish resistance of the metal usually make them unnecessary. The normal "water passivity" of the metal can be considerably increased by treatment with anodizing agent such as nitric acid, where this is practical. Normal "air passivity" of the metal can be increased with anodizing treatment agents such as nitric acid, where this is practical.
Treated thick deposits with hot nitric acid, chromic acid, or permanganate solutions for many hours, and stated that the passive chromium would no longer dissolve in hydrochloric acid, and was more noble than platinum. Thick deposits treated with hot nitric acid, chromic acid, or permanganate solution for many hours, and states that chromium is no longer passive akan dissolved in hydrochloric acid, and more noble than platinum. Except for nitric acid, such Treatments tend to discolor the surface chromium. Except for the nitric acid, such as the treatment tends to discolor the surface of chromium.
See anodizing in oxalic acid and other type of metallic coating such as chrome plating, bright chrome plating, white chrome plating, black chrome plating, dull black chrome plating, chrome plating solution. Anodizing process, black anodized product, red anodized product, bronze anodized color.
