11. Preparation and Properties of Surface Modified Thin Polymer Films
Sammanfattning : This thesis deals with preparation, modification and characterisation of thin polymer films. Most of the work has been performed using thin films of high-density polyethylene (HDPE) as a model system for systematic surface modifications by glow discharge plasma and UV/ozone treatments.

12. Low-temperature carburizing/nitriding of austenitic stainless steels - Influence of alloy composition on microstructure and properties
Sammanfattning : Austenitic stainless steels are among the most used materials in applications where corrosion resistance is important, as the food, pharmaceutical, chemical, oil and gas industries. However, low hardness and poor tribological properties is often an obstacle for their applicability. LÄS MER
13. Microstructural Characterization of Expanded Austenite in 304L and 904L Austenitic Stainless Steels
Sammanfattning : Austenitic stainless steels are among the most used materials in modern industry, mainly because of their superior corrosion resistance. However, low hardness and poor tribological properties often restrict their applicability. LÄS MER
14. Modeling of Intraluminal Surfaces of Thoracic Aortas
Sammanfattning : Vascular diseases are getting more and more common as a result of modern-day lifestyle and the fact that the population is getting older. One of the newest treatments for vascular diseases such as aneurysms and dissections is endovascular repair with endografting. LÄS MER
15. Managing Effects of Manufacturing Variation in Dental Medical Device Treatments - Increasing Geometrical Robustness
Sammanfattning : Today, there are many solutions for dental rehabilitation. A damaged tooth can be replaced with a dental crown, and a toothless patient can be rehabilitated with implants and a corresponding bridge set-up. Traditionally, a dental crown is manufactured by veneering porcelain to a metal surface that is obtained through the use of casting principles. LÄS MER
