Laboratory of anti-erosion wear-resistant materials and coatings

 

Laboratory of anti-erosion wear-resistant materials and coatings

 

The laboratory conducts research on the development of technologies for creating multilayer nanocomposite coatings that increase the abrasive, corrosion, and erosion resistance of materials used in high-power thermal equipment.

The full-time employees of the laboratory are 3 doctors of technical sciences, 3 candidates of technical sciences and 1 graduate student.

The laboratory has completed several government contracts and grants, published more than 15 papers in peer-reviewed scientific journals, including 5 articles indexed by Scopus.

The head of the laboratory is the head of the REC “Materials”, Doctor of Technical Sciences, prof. Varavka Valery Nikolaevich, tel. 8 (863) 273-84-42.
