  6. 4. Nanocrystalline Alumina-Zirconia Thin Films Grown by Magnetron Sputtering

    Author : David Huy Trinh; Hans Högberg; Marianne Collin; Lars Hultman; Ingrid Reineck; Mats Halvarsson; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Alumina-zirconia thin films have been deposited using dual magnetron sputtering. Film growth was performed at relatively low-to-medium temperatures, ranging from ~300°C to 810 °C. Different substrates were applied, including silicon (100), and industrially relevant materials, such as WC-Co hardmetal. READ MORE
