摘要

Cold spray is a powder consolidation process whereby metallic, polymeric, and/or combinations of metallic and non-metallic particles are consolidated to form a coating or a near-net-shaped-part by means of ballistic impingement upon a suitable substrate. To date the cold-spray process has been used primarily for dimensional restoration and to apply wear and corrosion, resistant coatings. However, advancements in the development of feedstock powders, process parameters, and cold-spray equipment have enabled the production of bulk cold-spray materials with superior properties, including increased strength and ductility comparable to those of wrought materials. The focus of this paper is to present materials characterization data of cold-spray aerospace aluminum alloys developed through collaborative research by the U.S. Army Research Laboratory, the United Technologies Research Center, and Worcester Polytechnic Institute that have been tested and qualified for use on military rotorcraft and fixed-wing aircraft.
