Abstract: A new method for the preparation of nanocrystalline ceramic films was proposed, and α-Al2O3 films were deposited On a Ni-Al alloy substrate and then heat-treated, the films with nanocrystalline structure were characterized by SEM and TEM. The process of the new method is as follows: an initial liquid is atomized and travels through a high temperature flame, chemical reactions taking place, and deposited on a substrate, then the film obtained is heat-treated.

Key words: nanocrystalline ceramic, combustion chemistry, deposition, α-Al2O3
