Chromium plating on kitchen faucet surface
Chromium is a silver-white, slightly blue-colored metal. The chrome coating has high hardness and wear resistance, and its hardness is second only to diamond. Chromium also has a strong passivation ability, is easily oxidized in the air, forms a very thin passivation film on the surface, and does not change in a humid environment, and can maintain the surface gloss for a long time, showing a similar appearance to a precious metal. It is very decorative, and it will not peel off when used for a long time. Therefore, chrome plating is the most commonly used processing method in the surface treatment of faucets.
