1. Decreasing porosity, with the formation rate of crystal nuclei exceeding the growth rate, promotes the refinement of the nuclei. 2. Enhancing bonding, it facilitates the breakdown of the passivation film, which is beneficial for a firm bond between the substrate and the coating. 3. Improving coverage and dispersion capabilities, the high cathodic negative potential allows deposition on the passivated areas during conventional electroplating, slowing down the "burning" and "branching" defects caused by excessive consumption of沉积 ions on the protruding parts of complex-shaped components. This can reduce the thickness of a given characteristic coating (such as color, non-porous) to 1/3 to 1/2 of the original, saving raw materials. Aviation Power
4. Reduces internal stress in the coating, making it easier to achieve crack-free coatings and reducing the need for additives. 5. Beneficial for obtaining alloy coatings with stable composition. 6. Improves anode dissolution without the need for anode activators. 7. Enhances the mechanical and physical properties of the coating, such as increasing density, reducing surface and bulk resistance, improving toughness, wear resistance, and corrosion resistance, while also allowing control over the coating's hardness. 400HZ power source.
