Welcome to my home page!
As I am the head of the Division of Materials Microstructure at Chalmers University of Technology it is perhaps not surprising that my main research tools are electron microscopes and their add-on equipment. The general aim is to understand how the microstructure of materials influences their properties. And of course to have ideas about how the microstructure could be changed in order to get better properties for the materials.
I work mainly with what is happening at the surface of a material when it is in use. My work can be divided into two categories. The first is the study of hard, wear protective coatings, such as k-, and a-alumina, TiC and TiN produced by Chemical Vapour Deposition (CVD) or Physical Vapour Deposition (PVD). The second concerns the high temperature corrosion of materials such as Fe-Cr stainless steel, molybdenum disilicide based composites and Fe-Cr-Al alloys.
