Functional coating:
The function of this kind of coating is to make the product have some special function under certain use conditions. The commonly used functional coatings are wear-resistant and anti-wear coating, hot working coating, solderable coating, conductive coating, magnetic coating and high temperature oxidation coating. Functional coating plays a special and important role in industrial technology.
Decorative coating:
This kind of coating can not only prevent the corrosion of the parts of the products, but also give the products and parts a glossy appearance that remains unchanged for a long time. This kind of coating is widely used, and it is mostly multi-layer, that is, first plating a "bottom" layer on the substrate, then a "surface" layer, and sometimes even an intermediate layer, because it is difficult to find a single metal coating. can meet the dual requirements of protection and decoration at the same time. Although some coatings have strong anti-corrosion ability, they can not maintain luster for a long time under the condition of use, and they are soft and easy to wear. Although other coatings have poor anti-corrosion ability, they can give products a pleasing glossy appearance and are not easy to wear out. By making use of the different advantages of the coating and proper matching, the multi-layer protective-decorative coating with both corrosion resistance and gloss and wear resistance can be obtained. In the past, copper-tin alloy was used as the underlayer of protective-decorative coating in China. Its anticorrosive ability is strong, but it is easy to oxidize and change color, and then it is plated with a bright chromium coating. It not only has a constant silver-blue luster, but also wear-resistant. Recently, the use of copper-nickel-chromium multi-layer protective-decorative coatings is increasing in China, such as cars, bicycles and watches.
