6. Preparation and characterisation of refractory whiskers and selected alumina composites
Sammanfattning : A whisker is a common name of single crystalline inorganic fibre of small dimensions, typically 0.5-1 μm in diameter and 20-50 μm in length. Whiskers are mainly used as reinforcement of ceramics. This work describes the synthesis and characterisation of new whisker types. LÄS MER
7. Fundamental aspects of HiPIMS under industrial conditions
Sammanfattning : Fundamental aspects of the high power impulse magnetron sputtering (HiPIMS) process and its implication for film growth under industrial conditions have been studied. The emerging HiPIMS technique exhibits a higher plasma density and an enhanced degree of ionisation of sputtered material as compared to conventional direct current magnetron sputtering (DCMS).

8. Magnetron sputtering of binary, ternary and multicomponent thin film borides and carbides
Sammanfattning : Design of new thin film materials with improved properties and functionality is an important research field in materials science. In this thesis, I have used magnetron sputtering to deposit new thin film materials, which should combine high hardness and high ductility with other properties such as low friction or a good corrosion resistance.

9. Computational prediction of novel MAB phases
Sammanfattning : The synthesis procedure of any materials system is often considered a challenging task if performed without any prior knowledge. Theoretical models may thus be used as an external input and guide experimental efforts toward novel exotic materials which are most likely to be synthesizable. LÄS MER
10. Venturing Further into the Field of 2D Materials and their Laminated Parent Phases
Sammanfattning : The field of 2D materials is a relatively young and rapidly growing area within materials science, which is concerned with atomically thin states of matter. Because of their intrinsic 2D morphology, 2D materials have exceptionally high surface to weight or surface to volume ratio. LÄS MER
