Electroplating related effects
The technology of using electrolytic cell principle to deposit metal coating with good adhesion but different performance and substrate material on mechanical products. Electroplated coatings are more uniform than hot-dip coatings and are generally thinner, ranging from a few micrometers to tens of micrometers. Through electroplating, decorative protective and various functional surface layers can be obtained on mechanical products, and workpieces with wear and processing errors can also be repaired.
In addition, there are different functions depending on various electroplating needs. For example:
1. Copper plating: used as a base to enhance the adhesion and corrosion resistance of the electroplating layer. (Copper is prone to oxidation, and after oxidation, copper green no longer conducts electricity, so copper plated products must be protected with copper)
2. Nickel plating: used as a base or for appearance, to enhance corrosion resistance and wear resistance (among which chemical nickel has a higher wear resistance than chromium plating in modern processes). (Note that many electronic products, such as DIN heads and N heads, no longer use nickel as a substrate, mainly due to the magnetic properties of nickel, which can affect passive intermodulation in electrical performance)
3. Plating: Improves conductive contact impedance and enhances signal transmission. (Gold is the most stable and expensive.)
4. Palladium nickel plating: improves conductive contact impedance, enhances signal transmission, and has higher wear resistance than gold.
5. Tin plated lead: improves soldering ability and is quickly replaced by other substitutes (due to the presence of lead, it is now mostly replaced with bright tin and fog tin).
6. Silver plating: improves conductive contact impedance and enhances signal transmission. (Silver has the best performance, is easy to oxidize, and also conducts electricity after oxidation)
Electroplating is a method of laying a layer of metal on a conductive body using the principle of electrolysis.
In addition to conductive materials, electroplating can also be used on specially treated plastics.
