Hafnium oxide coating to improve the oxidation behavior of Zirconium Diboride [PDF]

Journal of the European Ceramic Society
Hafnium dioxide (HfO2) coatings were successfully deposited on zirconium diboride (ZrB2) using reactive magnetron sputtering. After the oxidation at 1500°C or 1600°C, the mutual dissolution of HfO2 and thermally grown ZrO2 was observed which has resulted
