Pulse power sources significantly enhance the functionality of coatings during electroplating of gold, silver, nickel, tin, and alloys. When used for decorative and protective electroplating (such as decorative gold), they ensure uniform and bright coatings with excellent corrosion resistance. Pulse power sources also achieve higher purity in precious metal refining. They surpass traditional electroplating power sources, representing the direction of their development. Dual-pulse power sources provide finer electroplating and better surface finish compared to single-pulse sources. The reverse pulse anodic dissolution in dual-pulse sources rapidly recovers the concentration of metal ions on the cathode surface, leading to dense, bright coatings with low porosity and high pulse current density in subsequent cathodic cycles. Additionally, the reverse pulse anodic stripping significantly reduces the adhesion of organic impurities (including brighteners) in the coatings, resulting in high purity and strong resistance to discoloration. Dual-pulse power sources are 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 components.
