Abstrakt: The technological characteristics of magnetoabrasive treatment of blade bodies used as a finishing operation in blade reconditioning and as a preliminary one in applying thin-layer coatings are studied. Fatigue testing of compressor blades with various types of surface treatment of the blade body and with a multilayer coating has been performed. A multilayer TiN coating is shown to exhibit good adhesion to the base metal, and blades with this coating have a higher fatigue strength and a lower scatter of durability values than after finishing polishing.
