👉 Cathodic refers to a type of electrochemical process in which an electrode is placed on a metal surface, and the electrons are released from the surface. This process can be used for various purposes such as corrosion control, protection against chemical reactions, or even as a tool for cleaning and decontamination processes. In general, cathodic processes involve using a positive electrode (such as zinc oxide) to remove or neutralize unwanted substances on an electroplated metal surface. The negatively charged ions in
