Electropolishing

Electropolishing is the process of smoothing and/or brightening a metal surface anodically in a concentrated acid or alkaline solution. Anoplate is set up to perform it on either Stainless Steel or other Nickel rich alloys (such Kovar and Invar). While it can be done on many base metals as a preplate operation, it is commonly done on Stainless Steel as a final finish. It provides a chemically and physically clean surface and removes any mechanical surface asperities which may be detrimental to the production of uniform and pit-free electroplated surfaces or the future performance and appearance of a Stainless Steel product. It helps to deburr machined edges and holes as well as removes any imbedded iron from the manufacturing process. The current is greatest on the outside edges and outside corners of parts, which are left especially smooth. The longer the process is applied, the greater the amount of metal that is removed: holes can be enlarged, threads can be rounded, and sharp edges can be smoothed.
