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 γ‐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° to 1200°C, this coating was transformed to various transient aluminas without any noticeable change in the morphology.
