Cerium Conversion Coatings for Use in Corrosion Protection of Aluminum Alloys
University of Missouri System: Missouri University of Science and Technology
posted on 07/02/2009
A process for enhancing the corrosion resistance of an aluminum-containing component with a cerium based coating
Suggested Uses
• Aerospace applications or any area where long-term corrosion protection is essential
Advantages
• Environmentally friendly
• Reproducable
Detailed Description
A conversion coating employing cerium salts as the primary active agents has been developed to improve the resistance of aluminum to corrosion. The main use of the coating would be as a substitute for the environmentally undesirable chromate materials now being used. The cerium is deposited by means of an electrochemical process.
