1. On the Machining of Involute Helical Gears - Prediction models on tool geometry, cut gear tooth surface topography, chip geometry, and tool cutting forces
Sammanfattning : The modern requirements on power transmissions focus on energy efficiency, low noise and dynamic vibrations, and power density. In order to meet these requirements, the gear wheels must be manufactured to very high precision. Additionally, it should be economical to manufacture these gears within the tight requested tolerances. LÄS MER
2. On Polishability of Tool Steels
Sammanfattning : One of the world’s fastest growing industries is the plastic industry. Today’s ever increasing demands of high quality products, shorter lead times and reduced costs push development and research forwards. LÄS MER
3. Nanocomposite films for corrosion protection
Sammanfattning : This thesis describes technical and scientific aspects of new types of composite films/coatings for corrosion protection of carbon steel, composite films with nanometer thickness consisting of mussel adhesive protein (Mefp‐1) and ceria nanoparticles, and polymeric composite coatings with micrometre thickness consisting of conducting polymer and ceria nanoparticles in a UV‐curing polyester acrylate (PEA) resin.The influence of microstructure on corrosion behaviour was studied for a Fe‐Cr‐V‐N alloy containing micro‐sized nitrides with different chemical composition spread in martensitic alloy matrix.

4. On Surface Topography of Steel Sheet for Car Bodies
Sammanfattning : This thesis is a contribution to the scientific area of surface topography on sheet metal surfaces. The studies are restricted to exploring the influence of the steel sheet,s surface topography on forming properties and on appearance after painting. LÄS MER
5. Micro-grinding of titanium
Sammanfattning : Titanium and its alloys are difficult-to-cut materials, commonly used in several application fields, such as: medicine, aerospace, automotive and turbine manufacturing due to their biocompatibility, corrosion resistance, excellent mechanical and thermal properties, and light weight. However, its machining is associated with several difficulties, such as high tool wear, low surface quality, high cutting forces and high costs. LÄS MER
