Well-qualified researchers: 4 Dr. Sci., 5 Ph.D. and 25 engineers and auxiliary personnel.
At the core of an experimental infrastructure of department - a set of press equipment and furnaces.
We have a variety of tool set, designed for the manufacturing of various abrasive tools. Directly in our department, we investigate the microhardness of composites, we estimate the structure by means of optical microscopy and carry out the thermal analysis of new materials.
Collaboration interests
Our department is interested in participating in EU projects under FP8 program and also in other forms of international and projects in the following research areas: mechanisms of the structure formation
