The Effect and Advantages of the Chrome Plating Process of the Wire Shelving

The formation, effect and advantages of the chrome plating process of the wire shelving

Chromium is a kind of silvery white metal with a bluish tint, with a relative atomic mass of 51.99, a density of 6.98~7.21g/cm3, a melting point of 1875~1920℃, and a standard electric potential of Yosh/c, -0 .74V, old “/c,” -0.41V and P very e+/Cr shake -1.33V, metallic chromium is easily passivated in the air, and a very thin passivation film is formed on the surface, thus showing precious metals Nature.

The chrome-plated layer has a high hardness, and its hardness can vary in a wide range of 400-1200HV depending on the composition of the plating solution and the 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 fraction of friction of the chrome-plated layer, especially the dry friction coefficient, is the lowest among all metals. Therefore, the chrome-plated layer has good wear resistance. Look at the chrome-plated shelves of the product.

The chromium plating layer has good chemical stability and does not work in alkali, sulfide, nitric acid and most organic acids, but it can be dissolved in hydrochloric acid (such as hydrochloric acid) and hot sulfuric acid. In the visible light range, the reflectivity of chromium is about 65%, which is between silver (88%) and nickel (55%). Because chromium does not change color, it can maintain its reflectivity for a long time and is better than silver and nickel.
