Electrolytic processes (corrosion protection)

Electrolytic processes in corrosion protection use electrical currents and a conductive liquid (electrolyte) to protect or refine metallic surfaces against corrosion. This involves the targeted application of protective layers or the control of electrochemical processes in order to increase the service life and resistance of materials.

Galvanization is a well-known electrolytic process. In this process, the metal to be protected is immersed in an electrolyte bath while an electric current flows. This current causes metal ions to be deposited from the electrolyte onto the surface of the workpiece, forming a thin, dense layer. Typical coatings are zinc, chrome, nickel or copper, which offer different corrosion protection and wear properties depending on the application.

Another process is electrolytic passivation, in which protective oxide layers are formed on metals such as aluminum or stainless steel through electrochemical treatment. These layers act as a barrier against aggressive environmental influences and improve corrosion resistance.

These processes are used in numerous areas, such as the automotive industry, electrical engineering and construction. They offer the advantage that they enable targeted protective coatings with defined properties, such as hardness, gloss or chemical resistance. Professional implementation and consideration of environmental aspects, particularly when handling chemicals and electrolytes, are important for the effectiveness of these methods.
