Tips: The principle of pulse plating rectifier power supply
Understand the principle of pulse plating rectifier power supply can use plating rectifier more correctly. Pulse plating rectifier is a powerful method to improve the coating quality through the control method outside the tank. Compared with ordinary DC plating, it has more excellent properties (such as corrosion resistance, wear resistance, high purity, electrical conductivity, welding and good resistance to discoloration, etc.), and can greatly save rare and precious metals, therefore, it is better used in functional electroplating. At present, the square wave pulse is mostly used in pulse plating.
The pulse plating rectifier power supply can generate a square wave pulse current. When it is used in electroplating, it cannot obtain an ideal square wave, but a waveform similar to a trapezoid, which will affect the full play of the beneficial effect of the instantaneous high potential of pulse plating. The pulse frequency will also have a greater impact on the crystallization of the coating. The frequency is too low and the effect is not obvious. If the frequency is too high, the waveform distortion is large, and even the pulse current will become a DC current. The correct use of the pulse plating rectifier power supply (such as equipment installation, equipment selection, parameter selection, etc.) has an important impact on the pulse waveform, equipment reliability, and normal performance of the advantages of pulse plating.
