what is process in nickel chromium plant

The typical process consists of a primary copper layer, a secondary nickel layer, and the final chromium plating. Nickelplating itself is used for corrosion protection without additional chromium. Usually two nickel layers are plated from different plating baths. A nickel layer of dull finish covers a bright nickel layer.

  • Chrome plating   Wikipedia

    Chrome plating Wikipedia

    Chrome plating less commonly chromium plating, often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal object. The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. Sometimes, a less expensive imitator of chrome may be used for aesthetic purposes.
