High-quality chrome plating:
- The high-quality faucet is plated with semi-bright nickel, bright nickel and chrome on the fine copper body. In some cases, there is a copper plating process before the first layer, which can improve the surface flatness of the product and enhance the adhesion of electroplating (high-quality copper substrates rarely have copper plating processes, unless special requirements are required), thus Improve electroplating yield.
- Among the three-layer coatings, the nickel layer (including semi-gloss nickel and bright nickel) plays a role in anti-corrosion. The nickel is soft and dark, so a layer of chromium will be plated on the nickel layer to harden and brighten the surface. Among them, nickel plays a major role in corrosion resistance, and chromium is mainly used for aesthetics. So in production, the thickness of nickel is the most important. For normal faucet products, the thickness of nickel is more than 8um, and the thickness of chromium is generally 0.2~0.3um.
- Of course, except for the electroplating process, the faucet uses copper material and casting technology is the basis. If the copper material and casting technology is not good, no matter How many layers of nickel and chrome are plated, the faucte still is not good.
Inferior chrome plating:
- The thickness of the coating is only 3-4um, it’s too thin and will not last for a long time. It’s very prone to surface oxidation corrosion, blistering of the coating, and the whole coating falling off.
