Electropolishing is an electrochemical process that removes material from a metallic part, typically stainless steel or similar alloys. The part is immersed in a temperature controlled bath of electrolyte (typically mixtures of sulfuric acid and phosphoric acid). The part serves as the anode as it is connected to the positive terminal of a DC power rectifier. The negative terminal of the […]
What’s the difference in passivation and electropolishing?
As a non-electrolytic process, passivation uses solutions like citric and nitric acids instead of an electrical current used in electropolishing to create a inert oxide layer / film and remove free iron and foreign matter from metal surfaces. Electropolishing, a non-mechanical interactive process, can be used on objects with complex geometries. The electropolishing process uses a combination […]
How many amps of current will it take to electropolish a part?
The current or amps required to electropolish a part is primarily based on the surface area of the part or total surface area if multiple parts are desired to be electropolished at the same time. More information on electropolishing can be found on What is electropolishing? How does electropolishing work? page Visit the Electropolishing Current Required […]
How long will it take to electropolish a part?
The cycle time required to electropolish a part is primarily based on the current / amps and surface area of the part or total surface area and rectifer current if multiple parts are desired to be electropolished at the same time. Visit the Electropolishing Current Required Calculation Spreadsheet to calculate the approximate cycle time required for a […]
