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

during the consolidation of monomers and oligomers; the consolidation of glass and metal powders during the free and compression sintering; the formation of interphase surfaces in filled composites; the formation of precision surfaces of non-metal materials for optics and electronics; mechanisms of functioning and destruction of materials in the dynamic contact zone of solids; abrasive cutting mechanisms; the development of polymers, glassy and metal coatings for various purposes.

Potential role: major partner, scientific expert, technology provider.
