The monograph describes the issues of the current state of finishing the blades of the GTE compressor from titanium alloys, the main laws of the formation of the characteristics of the surface layer are considered. The results of tests for fatigue, impact strength and wear resistance of blades subjected to vibroabrasive treatment, ultrasonic and pneumatic-blast hardening with balls, magnetic-abrasive polishing with application of anticorrosive coatings are given.
