Auxiliary cathode

Auxiliary cathode electroplating is an electroplating metal coating process used in industry for the surface finishing of metal parts. This process enables the uniform and efficient deposition of metal layers on the workpieces to be coated.

In auxiliary cathode electroplating, additional cathodes are used to optimize the current distribution during the coating process. These auxiliary cathodes are often made of an inert material such as titanium or stainless steel. They are strategically placed to direct the electrical current to the parts to be plated and ensure uniform metal deposition.

A key factor in the use of auxiliary cathodes is the avoidance of uneven coatings on the main cathodes, especially on complex-shaped or large workpieces. The auxiliary cathodes ensure effective current distribution over the entire surface of the workpiece, resulting in a homogeneous and high-quality metal coating.

The use of auxiliary cathodes in electroplating is widespread in various industries, including the automotive industry, electronics production and heavy industry. By improving coating quality and uniformity, auxiliary cathode electroplating helps to create durable and aesthetically pleasing surfaces on metal components.
