The corrosion, microstructure, and hardness of nanocrystalline AA5083 were compared to that conventional AA5083-H116 consolidated gas atomized powder. was produced by consolidating high-energy ball milled powder with two methods: cold compaction spark plasma sintering. Electrochemical impedance spectroscopy, cyclic potentiodynamic polarization, Mott-Schottky analysis, immersion tests followed s...
