What is cathodic cleaning?

Cathodic cleaning refers to a technique used to remove contaminants and oxides from the surface of metals through electrolysis. This process is based on the principles of electrochemistry, where the metallic workpiece is connected as a cathode in an electrolytic cell. When an electric current is applied, the surface of the metal gets cleaned as the oxidized particles are reduced and become detached.

The ability to control the cleaning action by adjusting the imbalance in the electrochemical cell is pivotal to the effectiveness of cathodic cleaning. This allows the operator to tailor the cleaning process based on the specific requirements of the material being cleaned, such as the type and extent of contamination. By managing these parameters, the operator achieves optimal cleaning results while minimizing potential damage to the base material.

This method does not rely on mechanical or abrasive techniques, and therefore does not necessitate advanced equipment beyond the basic setup required for electrolysis. It is also designed to be suitable for a variety of metals, rather than being restricted to certain types, which enhances its versatility in industrial applications.
