Cathode

In electroplating, the term "cathode" refers to the counterpart of the anode in an electrolytic plating process. Here is an explanation:

The cathode is the negatively charged electrode material in a plating bath or electrolytic cell. During the electroplating process, metals are transferred from the anode to the cathode. The process is accomplished by electrolysis, in which an electric current flows through the plating bath.

During the electroplating process, metal ions released from the anode are drawn to the cathode. At the cathode, these metal ions are reduced and form a uniform metal layer on the surface of the workpiece or component to be electroplated. This process allows for the plating or coating of metals onto the target object.

Selection of the proper cathode, type of electrolyte, and control of the electrical current are critical to achieving the desired plating effects and ensuring an even and adherent coating on the workpiece.

The cathode plays an important role in various electroplating applications, including jewelry manufacturing, electronic components, coatings to improve durability and prevent corrosion, and many industrial applications.
