2. Synthesis and Characterisation of Magnetron Sputtered Alumina-Zirconia Thin Films
Sammanfattning : 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). LÄS MER
