Aerospace/Defense Industry Collaborative Research

Corrosion on test vehicles after accelerated corrosion testing in salt fog chamber

Despite the known hazards and restrictions, hexavalent chromium materials continue to be used in the aerospace/defense industry, due to the technical performance and economic challenges of transitioning to hexavalent
chromium free alternatives. The principal technical performance challenge is the perception that the long term corrosion inhibiting properties of the hexavalent chromium free alternatives are not as effective as the hexavalent chromium
containing materials. The economic challenge lies in the costs associated with adopting new processes and retraining.

The Toxics Use Reduction Institute (TURI) at the University of Massachusetts Lowell is collaborating with representatives from Lockheed Martin, Raytheon, Northrop Grumman, Bombardier, Metalast, NASA, Navy, Air Force, and the Army to investigate and evaluate various hexavalent chromium free materials and manufacturing processes.
