1. Tribology of self-lubricating polymer composites for hydropower applications
Sammanfattning : The ongoing global climate crisis and its impacts calls for urgent actions, such as significant reduction of CO2 emissions by introducing more renewable energy. This has led to a rapid integration of variable power sources, such as wind and solar power, into the electricity systems. LÄS MER
2. Tailoring of Transition Metal Silicides as Protective Thin Films on Austenitic Stainless Steel
Sammanfattning : The objective of this study is to make use of transition metal silicides in a novel way as protective thin films on engineering metals. It can then be possible to take advantage of the potentially good corrosion resistance of metal silicides while compensating for their brittle nature by the ductile bulk material. LÄS MER
3. Tribology of polymer composites for elevated temperature applications
Sammanfattning : Polymers as construction material are common in the industry. Although more recently the use of polymer composites in more demanding applications has increased, requiring more of them mechanically, tribologically and thermally. To enhance the properties various fillers are used, from common glass fibers to more advanced nanoparticles. LÄS MER
4. Semi-deterministic numerical simulations of wear on various scales : From chemo-mechanical effects to the wear of components in orbital type hydraulic motors
Sammanfattning : A costly effect, caused by the relative motion of machine components in contact, is wear. Solid surfaces come into contact when the lubricant film thickness is thin, resulting in locally high pressures and high wear rates. Components and machines will, due to this wear, eventually lose their functionality. LÄS MER
5. Tribology of Metal-Graphite Composites : A Study of Sliding Electrical Contact Surfaces
Sammanfattning : An environmentally sustainable production of electrical power is important for preserving the earth’s natural resources. In order to utilize this power as efficiently as possible, it is of great importance to minimize the losses, for example in sliding electrical contacts. LÄS MER
