Many terminals are electroplated during production. What are the effects of electroplating on terminals?
  1. Nickel plating has a wide range of applications. It can be used as a protective and decorative coating to protect the base material from corrosion or bright decoration on the surfaces of steel, zinc die castings, aluminum alloy and copper alloy; It is also often used as the intermediate coating of other coatings, on which a thin layer of chromium is plated, or a layer of imitation gold is plated, which has better corrosion resistance and more beautiful appearance.
  2. The stability of electroplated nickel layer in air is very high. Due to the strong passivation ability of metal nickel, a thin passivation film can be quickly formed on the surface, which can resist the corrosion of atmosphere, alkali and some acids.
  3. Electroless nickel plating has fine crystal and excellent polishing performance. The polished nickel coating can obtain a mirror like luster appearance and maintain its luster in the atmosphere for a long time.
  4. The hardness of nickel coating is relatively high, which can improve the wear resistance of product surface. Nickel coating is commonly used in printing industry to improve the hardness of lead surface. Due to the high chemical stability of metal nickel, some chemical equipment also commonly use thicker nickel coatings to prevent corrosion by media. Nickel plating is also widely used in functional aspects, such as repairing worn and corroded terminal block parts, and local electroplating by brush plating technology.
  therefore, electroplating can improve the performance of wiring terminals.
