Pulse power sources significantly enhance the functionality of coatings during gold, silver, nickel, tin, and alloy electroplating; for protective-decorative electroplating (such as decorative gold), they ensure uniform color, excellent brightness, and strong corrosion resistance.
Pulse power sources enhance the purity of precious metals during purification, surpassing traditional electroplating power sources and representing the direction of their development. Dual-pulse power sources offer finer electroplating and superior surface finish compared to single-pulse sources. Aerial ground power 2, 36V aerial power 1, 400Hz variable frequency power source 7, 115/200V power source 2, 27V DC power source 5, 400Hz power source 12, aerial power.
The anodic dissolution during the reverse pulse of a dual-pulse power supply rapidly restores the concentration of metal ions on the cathode surface, benefiting the use of high pulse current densities in subsequent cathodic cycles, resulting in a dense, bright coating with low porosity. The anodic stripping during the reverse pulse of a dual-pulse power supply significantly reduces the adhesion of organic impurities (including brighteners) in the coating, thus enhancing the purity of the coating and its resistance to discoloration. The dual-pulse power supply is suitable for electroplating of gold, silver, rare metals, nickel, zinc, tin, chromium, and alloys; electroforming of copper and nickel; coating of electrolytic capacitors; anodizing of aluminum and titanium products; and electrolytic polishing of precision parts.
