Gold electrodes for electroplating platinum/gold: principles, applications, and advantages

Electroplating is an electrochemical process widely used in the industrial field, through which a layer of metal or alloy can be deposited on the surface of a conductor. The application of gold electrodes in electroplating is mainly due to the high conductivity and stability of gold. Advanced Institute of Technology This article will discussGold electrode for electroplating platinum/goldProvide a detailed introduction, including its principles, applications, and advantages.

1、 Principle of gold electrode for electroplating platinum/gold

The gold electrode process of electroplating platinum/gold mainly involves three basic elements: electrolyte, anode (platinum/gold), and cathode (electrode to be gold-plated). During this process, platinum/gold at the anode dissolves in the electrolyte to form metal ions. These ions gain electrons at the cathode (gold electrode) and are reduced, depositing on the surface of the gold electrode.

Specifically, during the electroplating process, platinum/gold on the anode loses electrons under the action of an electric field, forming metal ions that enter the electrolyte. At the same time, the gold electrode on the cathode attracts metal ions in the electrolyte under the action of an electric field, and accepts electrons to reduce them to metal atoms, thereby depositing on the surface of the gold electrode.
