The presentation describes the microstructure, adhesion and shear test results for AA7050 deposited AA7050-T7451 substrates via the Cold Spray process using helium and nitrogen as the main process gas. A batch of gas atomized AA7050 powder sized to -270 mesh (<53 µm) was sieved to +625 (>20µm) to remove as many of the smaller particles as possible. A portion of the powder was thermally treated using a propriety process. Particle size distribution measurements were made for the powders in the as-received, sieved and sieve and thermally treated powders. Scanning electron images of the powder before and after the thermal treatment were taken. The AA7050 powder was deposited on AA7050-T7451 substrates in the as-received and as-received and thermally treated conditions. Microstructure analysis showed deformation characteristics of the powders. Deposits of all the powder/main gas combinations showed very good adhesion. The sear strength for the AA7050 deposited using helium was much higher than the shear strength of the samples produced using nitrogen. Adhesion and shear strengths produced using a hand held spray nozzle and a robot controlled spray nozzle were similar.
