1. Unsaturated Fatty Acids in Alkane Solution : Adsorption and Tribological Properties
Sammanfattning : Fatty acids and blends of fatty acids are used as friction modifiers and anti-wear additives in diesel fuels. A large part of some fatty acid blends are unsaturated fatty acids. Even though fatty acids have been thoroughly investigated, the adsorption and tribological behaviour of unsaturated fatty acids are no fully understood. LÄS MER
2. On the processing of starch consolidated high speed steel - Microstructure and tribological properties
Sammanfattning : This thesis focuses on processing of high speed steel (HSS) powder into components using starch consolidation (SC) and supersolidus liquid phase sintering (SLPS). The work consists of four parts. First, the possibilities and constrains of the SC process are investigated and the role of starch in the green body fabrication clarified. LÄS MER

5. Tribological behaviour of HVAF-sprayed WC-based coatings: : Role of process variables and binder chemistry
Sammanfattning : Tungsten carbide (WC) based metallic matrix coatings sprayed using high velocity air fuel (HVAF) technique have attracted increasing attention as they show excellent tribological performance in various wear conditions. In the HVAF method, particles’ in-flight temperature and velocity can be influenced by the process variables including nozzle configuration as well as feedstock particle size range. LÄS MER
