Method and Device for In-Service Repair of Magnesium, Aluminum and High-Strength Steel

The objective of this proposal is to develop a methodology for using the Cold Spray Process for in-service repair of magnesium, aluminum and high-strength steel. The process will focus on the development of corrosion resistant coatings and provide improved corrosion resistance with a minimal effect on the base materials properties. The performance of two portable systems will be evaluated. One system is a commercially available system that uses air and nitrogen as the carrier gas and the other system is a system that uses helium as the carrier gas. Evaluation criteria will include coating properties (density, adhesion, strength, and corrosion resistance), easy of use, cost and portability. The efforts will address coatings for magnesium, aluminum and high strength steels. The results of this effort will be used to establish the performance of the available portable systems and to define the requirements for a portable system that will meet the in-service requirements. The end result will be an environmentally friendly, economical, portable system that can be used to apply coatings for in-service repair of magnesium, aluminum and high strength steels used is aircraft.
