  2. 2. Synthesis and Characterisation of Magnetron Sputtered Alumina-Zirconia Thin Films

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : David Huy Trinh; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alumina; Zirconia; NaKeywords: Alumina; Zirconia; Nanocomposite; Sputtering; Thin-Film; PVD; TEM; EELS; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : Alumina-Zirconia thin films were grown on a range of substrates using dual magnetron sputtering. Film growth was achieved at a relatively low temperature of 450 °C and at higher temperatures up to 810 °C. The films were grown on well-defined surfaces such as silicon (100) but also on industrially relevant substrates such as hardmetal (WC-Co). READ MORE
