Functionally Graded Aluminum Metal Matrix Composite Cold Spray Coatings on Aluminum 7075 Substrate

Abstract

Aluminum alloys have widespread use in the aerospace and maritime industries due to their high specific strength, good corrosion resistance, and low cost. Gas dynamic cold spray, cold spray for short, is a thermal spray technique that is used for in-field repair of metallic surfaces to include aluminum. To improve the wear resistance of aluminum, the metal must be reinforced with a filler. Additionally, to prevent delamination issues with cold sprayed coatings, a compositionally graded coating is required. To date, there has not been a study on the cold spray of compositionally graded, dual-reinforced aluminum metal matrix composites (Al-MMC).
