Karazin University Scientists Successfully Develop Multilayer Carbide-Nitride Coatings under the EURIZON Program

Scientists at V. N. Karazin Kharkiv National University are actively working on the project "Development of Ceramic Coatings for Surface Modification of Structural Materials Using Cathodic Vacuum Arc Discharge Generating Highly Ionized Plasma Flows" as part of the EURIZON program.

The project is being implemented at the Education and Research Institute "School of Physics and Technology" and focuses on designing systems of carbide-nitride coatings with double or triple layers based on W and Nb matrices, synthesized from highly ionized plasma flows generated by vacuum arc discharge, followed by research into their structure and properties.

The team has already achieved significant results: coatings were deposited on stainless steel substrates, their microstructure and properties were studied, mechanical and tribological tests were carried out, and critical loads for coating failure were determined. Future research will assess the influence of multilayer coating architecture on changes in structure as well as tribological and mechanical performance.

The project is being carried out in collaboration with the Institute of Materials Science, Slovak University of Technology in Bratislava, which promotes the expansion of international scientific cooperation.

Project Leader: Professor Viacheslav Beresnev

Team Members:

• Professor Serhii Lytovchenko

• Associate Professor Inna Afanasieva

• Leading Engineer Bohdan Mazilin

• Junior Research Fellow Denys Horokh

• Senior Research Fellow Olha Maksakova

This project is yet another testament to the fact that Ukrainian science continues to progress and reach new heights even in challenging times. It highlights the importance of international cooperation and a strong commitment to innovation.
