Aerospace and transportation industries continue to show significant interest in lightweight and strong structural materials. A number of newly developed aluminum and magnesium alloys are emerging as viable materials options, due to their unique functional properties. However, their susceptibility to corrosion continues to be a limiting factor in widespread implementation. A coating solution to mitigate the corrosion issues associated with these materials has been developed via the electrodeposition of thermodynamically stable single phase nanostructured Al-X (X = Mn,Zr,Cr) alloys. Data show that these Al-X coatings have significantly improved pitting potentials, and salt spray performance as compared to the base high-strength wrought Al and Mg alloys. Further, the targeted nanostructure of these new alloys provides improved strength and hardness to the coating, imparting durability and wear resistance, making them ideal coatings for harsh environments.
