Chemical surface treatment of aluminum has a significant effect on the bonding characteristics and the applications in which adhesive bonding of aluminum is used. Chromic acid etching is one of the oldest and most widely conducted treatment methods in industry. Henkel Loctite often receives requests to perform the chromic acid etching process on aluminum but it can be hazardous and inefficient. An actual chromic acid etching system for aluminum was designed and compared to other surface treatment methods to determine if this system would be of benefit to the sponsor in the future.
