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).
