FIELD: application of coats on cylindrical surfaces , for example, engine cylinder liner. SUBSTANCE: proposed device includes body, hold-down and delivery mechanism made in form of sleeves mounted coaxially forming precision pairs together with body and two hollow cylinders with rods on which rubbing members are mounted, rod with air supply passages which is mounted in end section and distributing head with pipe unions; magnetostriction converter which is mounted in outer center portion of rod is electrically connected with ultrasonic generator. EFFECT: enhanced wear resistance of surfaces being treated; increased productivity of antifriction coat application procedure. 8 dwg
