Abstract:

Chromic acid anodizing CAA is an aluminum surface pretreatment currently used on military aircraft and equipment. Chromium VI, present in this process, is a carcinogen and federal, state and local environmental agencies have implemented legislation which restricts the use of this material. The Naval Air Warfare Center Aircraft Division Warminster investigated several alternatives to CAA including Sulfuric-Boric Acid Anodize, Sulfuric Acid Anodizing, and Phosphoric Acid Anodizing. Physical performance properties of these processes were characterized and as a result of this program, the MIL-A-8625 anodize specification was modified to include some of these alternatives.
