Automatic decorative hard chrome electroplating line  

Chrome plating refers to the act of plating chromium as a plating layer on other metals. Chromium is a kind of silver-white metal with a bluish tint. Metallic chromium is easily passivated in the air, and a very thin passivation film is formed on the surface, thus showing the properties of precious metals. The chromium-plated layer has a very high hardness, and its hardness can vary in a wide range of 400-1200HV depending on the composition of the plating solution and process conditions. The chromium-plated layer has good heat resistance. When heated below 500℃, there is no obvious change in gloss and hardness. The temperature above 500℃ starts to oxidize and discolor, and the hardness starts to decrease when the temperature exceeds 700℃. The friction coefficient of the chrome layer is small, especially the dry friction coefficient, which is the lowest among all metals. Therefore, the chrome-plated layer has good wear resistance.
