Electropolishing is an electrochemical process that removes material from a metallic work piece. It is used to polish, passivate, and deburr metal parts and is often described as the reverse of electroplating.
Electropolishing has many applications in the metal finishing industry because of its simplicity and it can be applied to objects of complex shape. Typical examples are electropolished stainless steel drums of washing machines and stainless steel surgical devices. Ultra high vacuum (UHV) components are typically electropolished in order to have a smoother surface for improved vacuum pressures, outgassing rates, and pumping speed. Electropolishing is also commonly applied to the preparation of thin metal samples for transmission electron microscopy because electropolishing does not cause mechanical deformation of surface layers usually observed when mechanical polishing is used.
Electropolish options available:
- 300 Series Stainless steel
- ASTM B-912-00
