摘要：

After analyzing the interaction of some possible substrate elements with alumina sol, iron was determined to be the most important element in the crystallization of alpha-Al2O3. Our experiment shows, however, that coating crystallization originates from the substrate-coating interface. Substrate surface crystallography seems to play a more important role than additives in alpha phase nucleation. When oxide powders were used as additives, iron, manganese and chromium increased crystallization. Since the substrate surface includes iron, manganese and chromium, crystallization behavior may be a result of a combination of topography and some chemical effects.
