Institute of Superhard Materials

The decision to organize a laboratory for cutting difficult-to-machine steels and alloys, from which department No. 20 began its activities, was made in March 1963. The first head of the department was an outstanding specialist in cutting materials, Doctor of Technical Sciences, Professor A.N. Rosenberg.

Scientific direction

Development of theoretical and practical foundations of processes for forming precision elements of complex-profile products by cutting and cold plastic deformation with tools made of hard alloys and NTM.

Main tasks:

1. Conducting scientific, exploratory and applied research in the field of promising resource-saving technologies of machining with tools made of NTM and hard alloys in order to develop the theory and practice of cutting processes and intensive plastic deformation.
2. Development of scientific foundations for increasing the service life of parts by cold plastic deformation by creating gradient structures that include fine-dispersed and nanostructures in the surface layer, including titanium and titanium alloys.
3. Conducting scientific, exploratory and applied research in the field of manufacturing medical implants from modern structural materials (sapphire, bioinert ceramic materials and metal alloys), including elements of the mobile connection of hip and knee joint endoprostheses.
4. Research and development of processes for manufacturing parts from powder materials with a given porosity using the method of localized radial pressing in a closed volume.
5. Development of theoretical foundations for shaping the profile of gear wheels in order to restore worn large-sized ones.
6. Development of scientific and technological foundations for creating processes for shaping complex-profile surfaces in axisymmetric blanks using the HPD method.
