ANALYSIS OF TRENDS IN APPLICATION OF NONABRASIVE ULTRASONIC FINISHING FOR COMPLEX SURFACES IN CORROSIVE MEDIA
Securing the necessary product performance specifications is one of the most important tasks of modern engineering. Currently, for their formation and obtaining the desired quality of the parts surface layer various methods of finishing and hardening treatment (FHT) by surface plastic deformation (SPD), one of which is a non-abrasive ultrasonic finishing (NAUF), are utilized. A rapid progress is observed in the research of NAUF treatment. However, there are several issues related to its application in practice. The article analyzes the tendencies of NAUF application in treatment of parts complex surfaces operative in corrosive environments. Also, the main directions of NAUF development are determined.
