21. Nanocomposites for Use in Sliding Electrical Contacts
Abstract : In this thesis nanocomposite materials for use in high performance electrical contacts are tested. Self mating silver as coatings on cupper substrates are the most used material combination in power connectors today. In this work two new concepts were tested. READ MORE

22. On tribological design in gear tooth contacts
Abstract : The correct tribological design will have a considerable effect on a gear’s service life and efficiency. The purpose of this thesis is to clarify the impact of variation in the gear tooth flank tribological system on the gear contact load capacity – to increase the understanding of how surface topography and lubricant interact.

23. TiC-based nanocomposite coatings as electrical contacts
Abstract : This Thesis concerns the advanced surface engineering of novel TiC-based nanocomposite and AgI electrical contact materials. The objective is to make industrially applicable coatings that are electrically conductive and wear-resistant, and have a low coefficient of friction. READ MORE

24. Tribological behaviour of polymers in lubricated contacts
Abstract : An important issue in hydropower and other industries is the increasing demand for introduction of environment friendly solutions. Mineral oil based lubricants have long been used in various sliding bearings in hydropower stations. READ MORE

25. Dynamics of Rotors Influenced by Rubbing Contacts
Abstract : This thesis concerns theoretical studies of the dynamical behaviour of a rotor interacting with its non-rotating surroundings. Rotor-stator rubs make the rotor system strongly non-linear, which leads to phenomena that are not seen for ordinary rotors. READ MORE
