As a core surface treatment technology, electroplating mainly serves the following four types of needs:
I. Protective Needs
By isolating the substrate from the corrosive environment through metal plating, it significantly improves the material's resistance to oxidation and corrosion. For example, galvanized coating protects steel substrates through a sacrificial anode mechanism, which is widely used in machinery and construction.
II. Functionality Enhancement
Conductivity/thermal conductivity optimization: gold or silver plating on the surface of electronic components can reduce contact resistance and enhance signal transmission stability.
Mechanical property improvement: hard chrome plating can increase the surface hardness of parts (up to 800-1000HV ), prolonging the service life of moving parts.
Special performance empowerment: copper plating of printed circuit boards through holes to achieve conductive interconnections, copper plating of antique crafts and oxidation treatment to achieve specific visual effects.
III. Decorative enhancement
Precious metal plating (e.g., gold-plating, rhodium-plating) can give luxury goods, such as jewelry and watches, a high-gloss surface, and at the same time, it also has the function of anti-discoloration. Chrome-plated decorative strips for automobiles are typical examples of industrial aesthetics applications.
IV. Process Adaptation Requirements
Intermediate Transition Layer: Copper plating is often used as the base layer of multi-layer plating to enhance the bonding strength of subsequent plating layers.
Dimensional Repair: By controlling the thickness of plating layer (with micron-level precision), the dimensions of worn-out parts can be repaired.
The technology has been infiltrated into automobile manufacturing (accounting for 40% of the plating volume). （This technology has penetrated into automotive manufacturing (accounting for more than 40% of the plating volume), the electronics industry (PCB plating accounted for 35% of the industry applications), aerospace equipment and other high-end fields, becoming an indispensable processing link in modern industry.
