What is Electropolishing

Electropolishing is an electrochemical metal finishing technique that removes surface imperfections and enhances the appearance of metals like stainless steel, aluminum, and titanium. It is used to polish, passivate, and deburr metal parts. It is often described as the reverse of electroplating. It may be used in abrasive fine polishing in microstructural preparation.  

How Does Electropolishing Work

While electropolishing stainless steel, surface preparation is crucial for optimal results. Therefore, first, the metal is cleaned up, getting rid of any dirt or grease. Then, it’s dipped into a special bath filled with a solution, like an acid or a base. 

Next, electricity is passed through the solution, positively charging the metal. This causes a gentle erosion of the metal’s surface, smoothing out any rough spots or bumps. Finally, the metal gets a protective layer. The process results in:

Electropolishing removes surface irregularities and imperfections, resulting in a smoother texture that enhances the metal’s appearance and feel.

By eliminating microscopic crevices and contaminants, it enhances the cleanliness of the metal surface, making it easier to sterilize and maintain hygiene standards.

The formation of a passive oxide layer during electropolishing improves the metal’s resistance to corrosion, extending its lifespan and suitability for harsh environments.
