Material Surface Treatment—Electropolishing
Electropolishing is an electrochemical process in which the atoms of a workpiece immersed in an electrolyte are converted into ions and removed from the surface by the passage of an electric current, thereby removing fine burrs from the workpiece surface and enhancing its brightness.
Suitable Materials:
1. Most metals can be electropolished; it is most commonly used for surface polishing of stainless steel (particularly suitable for austenitic nuclear-grade stainless steel).
2. Different materials must not be electropolished simultaneously; they must not even be placed in the same electrolyte solution.
Process Cost: The entire electropolishing process is largely automated, so labor costs are very low. Environmental Impact: Electropolishing uses relatively low-hazard chemicals, requires only a small amount of water, and is simple to operate. Additionally, it enhances the properties of stainless steel, helping to delay corrosion.
