Introduction of nickel plating on hardware springs

Matte nickel
   process introduction
Water-mist nickel & powder-mist nickel are the eutectoids of nickel and non-conductive particles, and the resulting coating has a matt surface; this coating can not only improve the corrosion resistance of the plated parts, but also obtain an elegant brocade-like satin Surface plated parts surface. Since the surface of the plated parts is matte like brocade, light reflection can be reduced. Therefore, it is suitable for parts such as automobiles, optical instruments and sewing machines; and because the appearance is similar to the surface of aluminum alloy after anodization, it is also suitable for building materials, furniture, plumbing equipment, music supplies, hardware tool parts and all kinds of jewelry, Jewelry accessories, etc. spring
   Process characteristics
   1. The appearance is elegant and beautiful, which can reduce light reflection.
   2. The surface has a soft metallic luster, and the human eye will not feel tired after watching.
  3. Good corrosion resistance.

  Double nickel plating
  Nickel is a silvery white and slightly yellow metal. The atomic weight of nickel is 58.69, the density is 8.9g/cm3, and the melting point is 1452°C. As the nickel-plated layer has many excellent properties, its application almost covers all sectors of modern industry. In the electroplating industry, the production volume of the nickel-plated layer is second only to the zinc-plated layer.
   Process characteristics
   1. The potential of nickel is higher than that of steel, especially nickel has a strong passivation ability, and the potential after passivation is higher, so for the steel substrate, the nickel layer is a cathodic coating.
  2. Adding additives based on Watt nickel, high leveling, high brightness, and the coating is brittle, not suitable for thick plating.
