METHOD OF FINISHING AND STRENGTHENING TREATMENT OF CYLINDRICAL SURFACES BY SHOT-BLASTING WITH ULTRASONIC CAVITIES

摘要

shot-blasting of cylindrical surfaces. SUBSTANCE: working mixture is accelerated by means of device shaped as turbine with nozzle assembly. Use is also made of electric motor, generator and ultrasonic disperser and their rotors are set on turbine. Steel or glass balls are used as a working mixture. Ultrasonic cavitation flow with formation of cavities is produced in working mixture. EFFECT: enhanced efficiency. 4 cl, 2 dwg
