1. On the friction and failure mechanisms of bearing and gear surfaces lubricated by a novel nanoadditive in highly stressed operating conditions
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Obtaining an enhanced lifespan for mechanical transmissions has become a challenge in diverse application sectors. Micropitting as a contact fatigue mechanism has seriously jeopardized the well-being of rolling-sliding elements present for instance in gearboxes. LÄS MER
2. Investigation of micropitting and wear in rolling/sliding contacts operating under boundary lubrication conditions
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : .... LÄS MER
3. SUSTAINABLE LUBRICATION FOR FUTURE TRANSMISSIONS : Micropitting performance of Glycerol-based lubricants
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Achieving sustainable lubrication by using environmentally friendly formulated lubricants has became an essential component of the transition process from fossil-powered vehicles to electrified transportation. Mixtures, or aqueous solutions of molecules such as polyhydroxy alcohols, and glycols usually known as green lubricants make it possible to achieve low friction coefficients under different lubrication conditions, which constitutes a potential alternative to improve the tribological performance of moving parts in automotive systems, at the same time that the environmental requirements are satisfied.

4. Evaluation of 25 MHz Ultrasonic Testing for Detection of Non-Metallic Inclusions in Steel
Uppsats för yrkesexamina på avancerad nivå, KTH/MaterialvetenskapSammanfattning : Quantification of inclusions is important since it is correlated to the steel’s fatigue properties. One method that could be further developed for detection of inclusions in steel is ultrasonic testing (UST). LÄS MER
5. Bearings in Wave Energy Converters
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Wave energy and wave energy converters is a fast rapidly developing field of research and energy harvesting. In recent years, more and more designs have seen operational success, and more and more are in development. LÄS MER
