Anodizing aluminum is an electrochemical process that produces a wear-resistant, corrosion-resistant aluminum oxide coating on the surface of aluminum parts. Aluminum anodizing is an electrolytic process carried out in an electrolyte such as dilute sulfuric acid. Current is passed through the part, causing negatively charged oxygen ions in the electrolyte to be attracted to positively…
