Properties and uses of common electroplated coatings.
1. Zinc coating is an anodic coating for iron and steel parts under atmospheric conditions. after color passivation, the protective performance of the coating is obviously improved and the appearance is improved. It is mainly used to prevent the corrosion of iron and steel parts, and its coating has the advantages of low price, excellent corrosion resistance and wide application.
2. Cadmium coating in the environment of ocean and high temperature atmosphere, cadmium coating is anodic coating for iron and steel parts. the coating is relatively stable, strong corrosion resistance and good lubrication performance, so it is widely used in aviation and electronic industry.
3. Tin coating is negative polarity coating for iron and steel parts. Therefore, steel parts can be mechanically protected from corrosion only when there are no pores in the coating. It has high chemical stability, almost no interaction with sulfur and sulfides, good weldability and shielding effect on nitriding.
4. Copper coating is a negative coating for zinc, iron and other metals, which is often used on iron and steel or some plastics as the bottom or intermediate layer of copper / nickel protective-decorative coating, as well as printed circuits, electroforming moulds and so on.
5. Nickel coating is a negative polarity coating for iron and steel parts, which has higher hardness, higher corrosion resistance than copper, alkali resistance and acid resistance. Commonly used for copper / nickel / chromium protection of iron and steel parts-the middle layer of decorative coating and pre-plating before acid copper plating.
6. Chromium coating is negative polarity coating for iron and steel parts. It has high heat resistance, good hardness, good wear resistance and strong light reflection at room temperature. it is widely used to improve the wear resistance, light reflection, repair size and decoration of parts.
7. Silver coating is a cathode coating for commonly used metals, which has excellent electrical conductivity, brazing properties and stable chemical properties. it is mainly used for conductive parts and welding parts in the electrical industry, as well as protective-decorative coatings. such as musical instruments, tableware, optical instruments and handicrafts.
