Low temperature formation of aluminide layers on nanocrystalline nickel

The study of the formation of aluminide coating on nanocrystalline and bulk nickel indicated that on bulk nickel a single layer of Al3Ni2 phase was formed, whereas on nanocrystalline nickel a single layer of Al3Ni2 and double layers of Al3Ni and Al3Ni2 phases were formed in short- and long-time aluminizing, respectively. The parabolic growth rate constant of single layer formed on nanocrystalline nickel was approximately 2–3 times greater than the bulk nickel.
