Pulse electroplating power supply is suitable for electroplating gold, silver, nickel, tin, and alloys, which can significantly improve the functionality of the coating; When used for protective decorative electroplating (decorative gold), it can make the coating color uniform and consistent, with good brightness and strong corrosion resistance; When pulse power is used for precious metal purification, the purity of precious metals is higher. Pulse power supply is superior to traditional electroplating power supply and is the development direction of electroplating power supply.
In the process of pulse electroplating, when the current is conductive, the pulse (peak) current is several times or even dozens of times that of ordinary DC current. It is precisely this instantaneous high current density that causes metal ions to be reduced at extremely high overpotentials, thereby making the grain size of the deposited layer finer; When the current is turned off, the discharge ions near the cathode area return to their initial concentration, and the concentration polarization is eliminated, which is conducive to the continued use of high pulse (peak) current density in the next pulse at the same time. At the same time, during the turn off period, there are also phenomena such as recrystallization and adsorption/desorption that are beneficial to the deposition layer. This process runs synchronously throughout the entire electroplating process, and the mechanisms involved constitute the most basic principle of pulse electroplating. Practice has proven that pulse power sources have incomparable advantages over traditional DC electroplating in refining crystallization, improving the physical and chemical properties of coatings, and saving precious metals. Firstly, through slow energy storage, the primary energy has sufficient energy; Then, the intermediate energy storage and pulse forming system is charged (or energy flows in), and the energy undergoes some complex processes such as storage, compression, pulse formation, or conversion, before finally being rapidly discharged to the load.
The main transformer of the pulse electroplating power supply is an efficient and energy-saving transformer independently developed by Tongke Electric. It uses nanocrystalline soft magnetic materials as the main transformer core, with a large over-current area, good cooling effect, excellent coupling, low operating losses, and a service life of more than 10 years; The main power component of the power supply is a high-power original imported Infineon insulated gate bipolar transistor IGBT module, with high-quality material selection to ensure quality. The output mode is full bridge full wave output, PWM control. Using RS-485 protocol for remote control is more convenient than traditional host control, reducing host losses; According to customer needs, LCD touch screens can be selected to avoid button and adjustment knob malfunctions caused by long-term operation in harsh environments.
