Abstract
Alumina (Al2O3)-zirconia (ZrO2) nanocomposite films were prepared by laser chemical vapour deposition. α-Al2O3-ZrO2 and γ-Al2O3-t-ZrO2 nanocomposite films were prepared at 1207 and 1000K, respectively. In the nanocomposite films, 10-nm-wide t-ZrO2 nanodendrites grew inside the α- or γ-Al2O3 columnar grains. The γ-Al2O3-t-ZrO2 nanocomposite films exhibited high nanoindentation hardness (28.0GPa) and heat insulation efficiency (4788Js-1/2m-2K-1).
