6. Friction and contact phenomena of disc brakes related to squeal
Sammanfattning : Brake squeal is a sound with a main frequency between 1 and 20 kHz, generated by an oscillation of the components of the brake system. The energy driving the oscillation is supplied by the friction between the disc and the pads. LÄS MER
7. Design, synthesis and characterisation of multilayered PVD coatings
Sammanfattning : Physically vapour deposited multilayered coatings were the target of this thesis.Several different wear resistant nitride coatings (TiN/CrN, TiN/MoN, TiN/NbN andTiN/TaN) have been evaluated. LÄS MER
8. Atom Probe Tomography of Hard Nitride and Boride Thin Films
Sammanfattning : Hard ceramic thin films, including TiSiN, ZrAlN, ZrB2, and ZrTaB2, with applications for wear-resistant coatings, have been studied using atom probe tomography and correlated with several other analytical techniques, including X-ray diffraction, electron microscopy, and elastic recoil detection analysis. Outstanding obstacles for quantitative atom probe tomography of ceramic thin films have been surmounted. LÄS MER
9. Piezoelectricity, Phase Stability, and Surface Diffusion in Multicomponent Nitrides
Sammanfattning : The last hundred years have been full of scientific discoveries leading to technological advances, such as, computers, smart phones, etc. Most of the advances would not have been possible without new discoveries within the vast field of materials science. LÄS MER
10. Study of Ni3Al- and MoSi2-based Materials for High Temperature Structural Applications
Sammanfattning : In general, the potential of current conventional high-temperature materials has been exploited to a large extent. The industries are therefore looking forward to development of alternative materials for their industrials application, which would be lighter, stronger and having improved higher temperature potential compared to the presently available alloys.
