Short description of current research

 

 

• Surface engineering for reduced friction and wear focused on development of PVD (physical vapour deposition) coatings. Examples are TiN, NbN, TaN, CrN, MoN, TiC, CrC, WC/C, TiB2 and multilayered and superlattice coatings including these. Also duplex coating (nitriding followed by PVD coating) is studied. A technique to produce nanocrystalline diamond coating of high wear resistance giving ultra low friction has also been invented. Applications are found in tools for metal cutting (turning, milling, drilling, sawing, etc.) and forming (extrusion, die casting, stamping, rolling, etc.) and in mechanical components such as bearings, seals, valves, cam/follower systems, gears, electrical contacts, etc.

 

• Mechanisms of friction and wear of tool steels, cemented carbides, ceramic materials and metal matrix composites are studied on a fundamental level in order to understand and further improve the tribological properties of these materials.

 

• Development of theoretical models for friction and wear, new analytical techniques and improved tribological test methods and test equipment is a continuing process.

 

• Recently I have explored the mechanisms of friction between skis and snow, with the intention to assist in ski preparation for optimum glide.

 

• Together with my colleagues at UU I have just revield the mechanisms behind the curling action of curlig stones, an about 500 years old secret. We have also suggested how to produce identical curling stones.

 

Current activities
He works 20% of full time at Uppsala university primarily by teaching at a the National Tribology School, and guiding two PhD students to their final exams. He participates in one large research project on gear manufacturing that involves 10 swedish companies including Volvo and Scania.
In addition he currently works as a consultant in tribology and materials science, and especially in developing materials for next generation (Gen IV) of nuclear power generators.
