Research interests: - Mechanisms of deformation and fatigue fracture in the surface layers of metals under alternating bending; - Hardening surface by ion-plasmous coatings - Influence of the thermal and chemical-thermal treatment on properties of metals - Development of laboratory technology of obtainment powder compositions by injection molding of complex shapes for manufacturing metal products with high physical and mechanical properties for the transport and space systems. Annually I have 450-500 hours of classroom instruction (lectures, laboratory and practical), the continuous management of scientific research works of students of 2-6 courses and diploma projects, production students practice guide. Currently, I teach discipline, "General Materials Science", "Functional Materials," "Thermal and Chemical-thermal treatment of metals", "Methodology of the selection of materials in engineering", including for students of China Shenyang Polytechnic University on the 2 + 2 program. Perform the duties of the senior curator of the department, supervisor training group 4B51, curator undergraduates, responsible (assistant head of the Department) for the research work of students and undergraduates. I am a member of the State Examination Board and State Examinations Commission.

Research results MAIN RESULTS OBTAINED FOR 2016-2017 Austenite stainless steel produced by metal injection molding (MIM process) is studied, including its structure, phase composition, and mechanical properties of initial feedstock and sintered material. Prepared feedstock consists of cylindrical granules with the diameter of approximately 3.5 mm. The main feedstock material is a mixture of chrome-nickel and steel powders. Polyacetal is used as a plastic binder. Upon sintering of the feedstock, the material is synthesized with chemical composition, structure, and mechanical properties similar to those of austenite stainless steels. The material density after sintering is higher than 98% of theoretical value. It is established that, upon sintering, a phase transformation occurs: the initial ferrite phase is transformed into the austenite phase. The phase transformation is promoted by nickel contained in initial powder mixture. The microhardness of the sintered material is 1.6 GPa; the elastic modulus is 115 GPa.
