Whats the difference between electropolishing vs. passivation? Are both necessary for processing a part? Which one should be done first? These common questions are often mistaken in industry because of specification callouts vs. true understanding of each process. Passivation Definition is… a non-electrolytic process typically using nitric or citric acid which removes free iron from […]
What is electropolishing? How does electropolishing work?
This video explains what electropolishing is and how electropolishing equipment works to remove burrs and polish parts. 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) and the part serves as the […]
