    Theplating processstarts with agoldstrike treatment to prevent the exchange reaction. The same strike bath can be used for the first rinse after thegold plating. The current density depends a lot on the processing method; that is, 0.2–0.4 Adm −2 is used for barrelplatingand 0.5–1 Adm −2 for rackplating.

    Electroplating Process BYJUS

    Theelectroplating processuses an anode and a cathode. Inelectroplating, the metal dissolved from the anode can be plated onto the cathode. The anode is provided with direct current, oxidizing and dissolving its metal atoms in the electrolyte solution. At the cathode, the dissolved metal ions are decreased and the metal is placed on the product.
