6. 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
7. Investigations of the corrosion resistances of magnetron sputtered multicomponent materials : A study on high entropy alloys, high entropy sublattice ceramics, and metallic glasses
Sammanfattning : The corrosion resistances of sputter deposited AlCrNbYZrN, CrNbTiTaWC and TaNiSiC alloys were assessed in acidic and alkaline environments. Compositionally complex alloying strategies, and whether they produced coatings with superior corrosion resistances, were explored. LÄS MER
8. Modeling High Power Impulse Magnetron Sputtering Discharges
Sammanfattning : HiPIMS, high power impulse magnetron sputtering, is a promising technology that has attracted a lot of attention ever since its appearance. A time-dependent plasma discharge model has been developed for the ionization region in HiPIMS discharges. LÄS MER
9. Development and tribological characterisation of magnetron sputtered TiB2 and Cr/CrN coatings
Sammanfattning : The aim of this thesis was to develop wear resistant physical vapour deposited coatings of TiB2 as well as multilayers of Cr/CrN. The correlation between deposition parameters and fundamental coating properties such as microstructure, composition, residual stress and hardness has been investigated. LÄS MER
10. Alumina Thin Films : From Computer Calculations to Cutting Tools
Sammanfattning : The work presented in this thesis deals with experimental and theoretical studies related to alumina thin films. Alumina, Al2O3, is a polymorphic material utilized in a variety of applications, e.g., in the form of thin films. LÄS MER
