High performance, thermodynamically stable, nanocrystalline metallic alloy coatings were successfully developed via a novel electro-deposition process. Using a reverse pulse process, a reduced grain size and a super saturated solid solution were simultaneously achieved. These nanomaterials are free of secondary phases resulting in reduced pitting corrosion and micro-galvanic corrosion. By engineering the grain size into the nano regime, we will show how the mechanical properties, corrosion and wear resistance improve as grain size is reduced. We will report here as well on the fatigue behavior of nanocrystalline Al alloys which show significant promise to boost performance. Characterization of various nanocrystalline alloy coatings of Ni, Ag and Al and the fundamental mechanisms of creating stable nanocrystalline structures will be presented. These improvements in properties make the nanocrystalline materials made by electrodeposition an ideal candidate for use as coatings or electro-additive manufacturing materials for aerospace, electronics, and automotive industries.
