Anodizing is a conversion of the aluminum surface to a thicker, corrosion-resistant aluminum oxide. This site-within-a-site covers everything from chromic and sulfuric acid anodizing to hard coat anodizing articles, suppliers and products. Check out our feature stories, tips from industry experts, and the latest in innovations from world-class suppliers.

Correlation Between Electrochemical Behavior and Neutral Salt Fog Corrosion on TCP Coated AA2024

A correlation was found between electrochemical properties and the corrosion of a trivalent chromium pretreatment (TCP) coated aluminum alloy (AA2024-T3) during neutral salt fog exposure.  Differences in open circuit potential, electrochemical impedance spectroscopy and Tafel analysis were observed and quantified between the best- and worst-performing processes.  a link was shown between electrochemical behavior and neutral salt fog corrosion resistance to predict which processes will provide the most corrosion resistant TCP coatings in a significantly shorter time than a full neutral salt fog test.
