Electropolishing is an electrochemical process used to smooth and polish metal surfaces. It involves immersing the metal in an electrolyte solution and applying an electric current. This current removes a thin layer of material from the surface, resulting in a shiny, smooth finish. This technique is commonly used on metals like stainless steel and aluminum to enhance their appearance and improve corrosion resistance. Electropolishing is often employed in industries such as medical, aerospace, and food processing, where cleanliness and surface quality are critical for performance and safety.
