摘要：

A simple method for the preparation of nanostructured aluminate coatings based on the hydrolysis of aluminum nitride powder is described. The coatings were successfully deposited on a sintered yttria-stabilized tetragonal zirconia (Y-TZP) ceramic substrate. The nanocrystalline coating formed using this method consists of gamma-AlOOH (boehmite) in the form of 6-nm-thick and 240-nm-long interconnected lamellas. During a subsequent heat treatment in the temperature range from 900 degrees to 1200 degrees C, this coating was transformed to various transient aluminas without any noticeable change in the morphology.
