1. Surfaces Designed for High and Low Friction
Abstract : This thesis comprises tribological studies of extremely well-defined surfaces of different designs. Both low-friction and high-friction surfaces were manufactured and experimentally evaluated.In the low-friction studies, lithography and anisotropic etching of silicon was first used as a texturing technique.

2. Formation and Function of Low-Friction Tribofilms
Abstract : The use of low-friction coatings on machine elements is steadily increasing, and they are expected to play an important role in the reduction of fuel consumption of future motorized vehicles. Many low-friction coatings function by transformation of the outermost coating layer into tribofilms, which then cover the coating surface and its counter surface. READ MORE

3. Surface Force and Friction : effects of adsorbed layers and surface topography
Abstract : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. READ MORE

4. Friction in threaded fasteners : Influence of materials and tooling
Abstract : Threaded fasteners represent the most common type of machine element, with a unique function that facilitates ease of assembly and disassembly. This ease of disassembly allows machine parts to be reused, refurbished, and recycled. READ MORE

5. The Friction between Paper Surfaces
Abstract : The main objective for the work described in this PhD thesiswas to formulate a friction model to characterize thefrictional behavior of paper. More specifically, the modelshould explain a phenomenon that is typical for paper grades,viz.: that the level of paper-to-paper friction is dependent onthe direction and the number of previous slides.
