Dry electropolishing

One of the most advanced and efficient techniques for improving the surface quality of metals is electropolishing. This method removes impurities, imperfections and traces of oxidation from metal surfaces, making them smoother, cleaner and more resistant to corrosion. A more recent development in this area is dry electropolishing, a technique that combines the advantages of conventional electropolishing processes with additional environmental and efficiency benefits.

Dry electropolishing is an innovative process for the surface finishing of metals that, unlike conventional electropolishing, does not use liquids such as electrolytes or acids. Instead, the process takes place in a dry environment using specially developed electrodes and a regulated electrical voltage.

In dry electropolishing, the metal surface to be processed is placed between two electrodes, one of which consists of a porous material such as foam or a special non-woven fabric. The other electrode consists of the metal to be polished itself. The application of an electrical voltage between the electrodes creates an electrochemical process that results in material being removed from the metal surface. This removal process is precise and uniform, resulting in a smooth, high-quality surface.

Dry electropolishing offers several advantages. It is more environmentally friendly, as no harmful chemicals are needed, and it does not generate harmful waste. In addition, the process is very precise and allows for the finishing of complex shapes and hard-to-reach areas. The resulting surfaces are shiny, clean and corrosion resistant. This makes dry electropolishing an attractive option for industries that require high-quality surface finishing without the drawbacks of conventional methods.
