Research programs

The scientific aim of the group conforms to the material science paradigm: understanding of the synthesis, microstructure evolution and fundamental knowledges of material properties of nanostructured materials of industrial interest. We work with both expermients and theory in order to gain deeper understanding on the material evolution on the nanoscale.

Hard coatings

Nanostructured hard coatings can be used as protective layers for e.g. cutting tools in order to extend the cutting inserts life time. We focus on developing new generation of novel hard coatings used as wear protection for cutting tools in close collaboration with industries, including Sandvik Coromant, Seco Tools, Ionbond Sweden and Plansee material composite.

Both experimental and theoretical studies are performed to observe, explain, and predict the properties of the thin films. In the experimental part, physical vapor deposition techniques, i.e. cathodic arc deposition and magnetron sputtering, are used to synthesize the coatings. Computational methods, such as phase field simulations, are also involved in the design of the new coating composition and the simulation of the decomposition mechanism.

Mesoporous materials and catalysis

Mesoporous materials have pores in the size range of 2-50 nm, and large available surfaces (500-1000 m2/g). They are used in applications such as catalysis, drug delivery, and templating.

In Nanostructured Materials, we focus on how the process parameters affect the material properties of mesoporous silica with cylindrical pores, SBA-15. Also, doping of the silica structure is performed, and the material is used as a template for nanoparticle growth for catalytic applications.

Engineering Materials

Aluminum alloys used as either cast automotive engine blocks or heat exchangers are studied. The influence of small (ppm-level) additions of alloying elements on the microstructure evolution during both solidification and brazing is of special interest
