Basic principles of electroplating process

2021-12-14

Electroplating is an electrochemical process as well as a redox process. The basic process of electroplating is to immerse the parts in a metal salt solution as the cathode, and the metal plate as the anode. After connecting to the DC power supply, the required deposits are deposited on the parts Plating. Anodes are divided into soluble anodes and insoluble anodes. Most anodes are soluble anodes corresponding to the coating, such as zinc anode for zinc plating, silver anode for silver plating, tin-lead alloy anode for tin-lead alloy plating, but a few electroplating Because the anode is difficult to dissolve, insoluble anodes are used. For example, acid gold plating uses mostly platinum or titanium anodes. The main salt ions of the plating solution are supplemented by adding a prepared standard gold-containing solution. The chromium plating anode uses pure lead, lead-tin alloy, Lead-antimony alloy and other insoluble anodes.
