Cold Spray for Repair of Magnesium Components

Abstract

The U.S. Army has experienced significant corrosion problems with magnesium (Mg) alloys that are used to fabricate aircraft components. The most severe of these are associated with large and expensive transmission and gearbox housings for rotorcraft, which have to be removed prematurely because of corrosion. Many of the parts cannot be reclaimed because there is not technology that can restore them adequately for service. The U.S. Army Research Laboratory (ARL) has developed a Cold Spray process to reclaim Mg components that shows significant improvement over existing methods. Part of this program has demonstrated and validated a Cold Spray (supersonic particle deposition) process using aluminum (Al) and/or alloys as a cost-effective, environmentally acceptable technology to provide surface protection and a repair/rebuild methodology to a variety of Mg alloy components for use on Army and Navy helicopters and advanced fixed-wing aircraft.
