1. Polymers in Aqueous Lubrication
Sammanfattning : The main objective of this thesis work was to gain understanding of the layer properties and polymer structures that were able to aid lubrication in aqueous media. To this end, three types of polyelectrolytes: a diblock copolymer, a train-of-brushes and two brush-with-anchor mucins have been utilized. LÄS MER
2. Elastohydrodynamic lubrication : interferometric measurements, lubricant rheology and subsurface stresses
Sammanfattning : .... LÄS MER
3. Transient elastohydrodynamic lubrication : Effects of geometry, surface roughness, temperature, and plastic deformation
Sammanfattning : The urgent need to reduce greenhouse gas emissions in combination with an increased use of sustainable energy resources have led to immense efforts on improving energy efficiency of mechanical systems. Consequently, modern machine elements are typically lubricated with low viscosity oils and designed to endure an increasingly high power density. LÄS MER

5. Experimental approaches to powder filling and lubrication in powder die pressing
Sammanfattning : There is a continuous need to improve the mechanical properties of steel parts produced through powder metallurgy in order to ensure the market growth of this sector and competitiveness against alternative production techniques. One of the more promising routes able to achieve this is to aim for components with higher densities. LÄS MER
