Our surface treatment processes include electroplating, electroplating, electrophoresis, and PVD, which are used to improve the appearance, corrosion resistance, wear resistance, and other properties of materials. Here is a brief introduction to them:
1. Electroplating
Principle: Using the principle of electrolysis, deposit a layer of metal or alloy on the surface of a conductive substrate. By using the workpiece as a cathode, metal ions are reduced and deposited on the surface of the workpiece under the action of an electric field.
Application: Commonly used to improve the corrosion resistance, wear resistance, conductivity, or appearance of workpieces (such as chrome plating, nickel plating, gold plating, etc.).
Advantages: Uniform coating, precise thickness control, suitable for various metals.
Disadvantages: May cause environmental pollution (such as electroplating waste liquid) and require conductive substrates.
2. Water plating (electroless plating)
Principle: Metal coating is deposited on the surface of the substrate through chemical reaction without the need for external current. Usually, reducing agents are used to reduce metal ions to metal atoms and deposit them on the surface of the workpiece.
Application: Commonly used for metallization of non-conductive materials (such as plastics) or uniform coating of complex shaped workpieces.
Advantages: No need for power supply, uniform coating, suitable for non-conductive materials.
Disadvantages: The control of coating thickness is not as precise as electroplating, and the cost is higher.
3. Electrophoretic Deposition (EPD)
Principle: Using the action of an electric field, charged particles (such as paint particles) are moved in the liquid and deposited on the surface of the workpiece. Commonly used in painting processes.
Application: Mainly used for painting in industries such as automobiles and home appliances, providing uniform coatings.
Advantages: Uniform coating, suitable for complex shaped workpieces, and good environmental friendliness.
Disadvantages: Mainly used for non-metallic coatings, limited functionality.
4. PVD (Physical Vapor Deposition)
Principle: Metal or compound materials are vaporized through physical methods such as evaporation, sputtering, etc., and then condensed on the surface of the workpiece to form a thin film.
Application: Used for preparing high hardness, wear-resistant, corrosion-resistant films (such as TiN, CrN, etc.), widely used in tools, molds, decorative parts, etc.
Advantages: Excellent coating performance, good environmental friendliness, and the ability to deposit various materials.
Disadvantages: High equipment cost, complex process, and thin coating thickness.
