  2. Electroplating - Wikipedia

    en.wikipedia.org/wiki/Electroplating

    Simplified diagram for electroplating copper (orange) on a conductive object (the cathode, "Me", gray). The electrolyte is a solution of copper sulfate, CuSO 4 in sulfuric acid. A copper anode is used to replenish the electrolyte with copper cations Cu 2+ as they are plated out at the cathode.

  3. Copper electroplating - Wikipedia

    en.wikipedia.org/wiki/Copper_electroplating

    Copper plating on aluminium. Copper electroplating is the process of electroplating a layer of copper onto the surface of a metal object. Copper is used both as a standalone coating and as an undercoat onto which other metals are subsequently plated. [1]

  4. Nickel electroplating - Wikipedia

    en.wikipedia.org/wiki/Nickel_electroplating

    Nickel electroplating is a process of depositing nickel onto a metal part. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. [ 3 ] To clean and protect the part during the plating process, a combination of heat treating , cleaning, masking, pickling , and etching may be used. [ 1 ]

    Such Zinc electroplating or Zinc alloy electroplating maintains a dominant position among other electroplating process options, based upon electroplated tonnage per annum. According to the International Zinc Association, more than 5 million tons are used yearly for both hot dip galvanizing and electroplating. [ 1 ]

  6. Chrome plating - Wikipedia

    en.wikipedia.org/wiki/Chrome_plating

    Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. A chrome plated part is called chrome , or is said to have been chromed .

    en.wikipedia.org/wiki/Metallurgy

    A simplified diagram of electroplating copper on a metal. Electroplating is a chemical surface-treatment technique. It involves bonding a thin layer of another metal such as gold, silver, chromium or zinc to the surface of the product. This is done by selecting the coating material electrolyte solution, which is the material that is going to ...
