The size of the metal surface treatment market will grow significantly in the next five years, with a CAGR of 6.2% during the forecast period, and the global chemical surface treatment market is forecast to reach US$19.3 billion in 2027. In particular, the growth of the Asia-Pacific region is very fast, far exceeding that of other regions; the growth rate in Europe is larger and will slow down due to the impact of the conflict between Russia and Ukraine, but the overall rate is also relatively high.

Electroplating process and types

1. Galvanizing: The main function of galvanizing on metal parts is anti-corrosion. The amount of galvanizing accounts for 1/3 to 1/2 of all electroplated parts. It is the most productive type of plating among all electroplating varieties. Galvanized has the advantages of low cost, good corrosion resistance, beautiful appearance, and storage resistance, and is widely used in industries such as light industry, electromechanical, agricultural machinery, and national defense.

2. Tin plating: The corrosion products of tin are harmless to human beings and are easy to break. Tin plating is widely used in food canned packaging products, drinking utensils, tableware, and many parts that need to be brazed in the electronics industry.

3. Nickel plating: Nickel plating has a wide range of applications and can be used for both protective decorative coatings and functional repair plating. Used for household appliances, hardware products, automobiles, and other parts.

4. Chrome plating: Chrome can maintain luster for a long time in the atmosphere. The chrome plating layer has high hardness, excellent wear resistance, and low friction coefficient. Therefore, chrome plating is often used for protective decorative coatings to prevent the base metal from rusting and beautifying the appearance.

5. Brush plating: The metal positive ions in the plating solution obtain electrons on the surface of the workpiece (cathode) under the action of the electric field force and deposit on the surface to form an electric forging layer. The thickness of the coating can reach 0.01-0.5mm, the quality of the coating is good, and the bonding strength is high.
