The Corrosion and Surfaces Laboratory at the University of Rhode Island investigates degradation of materials and methods to mitigate degradation of materials, such as coatings. Interests include mechanisms of corrosion, corrosion assisted fatigue, hydrogen embrittlement, alternates to chromates, adhesive bonding, residual properties after explosions, bio composites and failure analysis.
Chromate replacement technology:
An alternate to chromates for aluminum alloys was developed, patent 6,706,207, at URI. Further research is continuing to improve the protection provided. At present this project is investigating Al 5086 before and after sensitization to optimize the process for maximum corrosion protection.
Surface treatment for paint adhesion:
An investigation of surface treatments for both galvanized and metalized steel to promote paint durability is being undertaken.
