What Chemical Is Used For Electropolishing?
Electropolishing typically uses an electrolytic solution, which is a mixture of an acid and a solvent. The specific type of acid used can vary depending on the polished material and desired finish.
Commonly used acids for electropolishing include sulfuric acid, phosphoric acid, and nitric acid. The solvent used in the electrolytic solution is typically water or an alcohol-based solution. The electrolytic solution is applied to the material being polished, and an electric current is passed through it, causing a controlled erosion of the material’s surface to create a smooth and shiny finish.
