Research and development of the technology for restoring the blades of the gas turbine engine after operation by laser surfacing

The paper presents the research and development of the technology for restoring the blades of a gas turbine engine made of ZhS6U alloy after operation by laser pulse surfacing. Metallographic examination and control by the luminescent method at the places of surfacing were carried out. A technology for eliminating defects that occur on the blades during operation has been developed and tested.
