1. 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
2. Tribological behaviour of polymers in lubricated contacts
Sammanfattning : 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. LÄS MER
3. Tribological Behaviour of Pb-free Engine Bearing Materials
Sammanfattning : Engine bearings are amongst the most critical components of an internal combustion engine that support and allow smooth rotation of the crankshaft. They are designed to operate under hydrodynamic lubrication condition where the bearing and shaft surface are separated by a thick lubricant film. LÄS MER
4. 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
5. Polymeric Materials for Bearing Applications : Tribological Studies in Lubricated Conditions
Sammanfattning : One of the most important demands in hydropower and other industries today stems from the emphasis on preserving the environment. Usage of mineral and synthetic oils in sliding bearings of hydropower plants raises concerns about the environmental impact of these lubricants in case of spillage into downstream water. LÄS MER
