2500A +25V -25V Polarity Reversing Electroplating Rectifier for Surface Treatment

Electroplating is the process of applying a thin layer of other metals or alloys on the surface of certain metals by electrolysis. It is a process of applying a metal film to the surface of metals or other materials to prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics.



Types of plating

1. Copper plating: priming, enhance the ability to adhere to the plating layer, and the ability to resist corrosion.
2. Nickel plating: priming or appearance, to enhance the corrosion resistance and wear resistance.
3. Gold plating: improve the conductive contact impedance, enhance signal transmission.
4. Palladium-nickel plating: improve the conductive contact impedance, enhance signal transmission, wear resistance than gold.
5. Tin-lead plating: improve soldering ability, soon to be replaced by other substitutes.
6. Silver plating: improve the conductive contact impedance, improve signal transmission.

Elements of electroplating

1. Cathode: the plated object, referring to various connector terminals.
2. Anode: If it is soluble anode, it is the metal to be plated. If it is insoluble anode, most of them are precious metals (white gold, iridium oxide).
3. Plating solution: plating solution containing ions of the metal to be plated.
4. Plating tank: The tank that can bear and store the plating solution, generally considering strength, corrosion resistance, temperature resistance, etc.
5. Rectifier: The equipment to provide DC power supply.
