21. Engineering Ceramics for Tribological Systems. Manufacture, Properties and Testing
Abstract : A broad range of commercial and experimental grades of ceramics and ceramic composites was tested in various model tests and simplified component tests. The tests were done to establish important microstructural features, friction and wear mechanisms. READ MORE

22. Electro-Interfacial Composition Control by Ionic Liquid Technology : Nanostructure, Self-Assembly, and Friction
Abstract : Given the potential of ionic liquids (ILs) for batteries, supercapacitors and advanced lubricants, it is crucial to understand how electric fields affect the interfacial behaviour in IL-solvent systems and the intricate relationship between nanostructure and tribotronic properties. This thesis investigates the structural and compositional changes of ILs with different solvents at electrified interfaces. READ MORE

24. Rough surface elastohydrodynamic lubrication and contact mechanics
Abstract : In the field of tribology, there are numerous theoretical models that may be described mathematically in the form of integro-differential systems of equations. Some of these systems of equations are sufficiently well posed to allow for numerical solutions to be carried out resulting in accurate predictions. READ MORE

25. Elasto-hydrodynamic film formation in heavily loaded rolling-sliding contacts : Influence of surface topography on the transition between lubrication regimes
Abstract : To meet the stringent demands set on future gear transmissions, and to allow for manufacturers to make them more efficient and durable, it is essential to understand what mechanisms that govern their performance. This work was launched with the chief targets of establishing key competence in gear lubrication. READ MORE
