Igor Ryabtsev works in the E. O. Paton Electric Welding Institute since 1972 as a researcher and since 1997 as the head of the surfacing department.The main areas of scientific activity are related to the study of physical and metallurgical processes of the most common surfacing methods (arc, electroslag, plasma powder, etc.), the development of new types of surfacing materials and technologies for surfacing parts operating under conditions of various types of wear, including parts metallurgical equipment: rolling rolls of various types, rollers of continuous casting machines, roller table rollers, etc. He investigates the features of inheritance and structure formation in the system surfacing material-weld pool-deposited metal with various surfacing methods. Based on these studies, the principles of controlling the structure and properties of the deposited metal for various purposes have been developed.
