Abstract:
A method for repairing a radial energy transfer surface of an ultrasonic rotary horn comprising a shaped metal horn body and the radial energy transfer surface with a deteriorated metal condition thereon, the method comprising:removing from the radial energy transfer surface a radial depth of metal which comprises the deteriorated metal condition to yield an ultrasonic rotary horn having a radial surface free from the deteriorated metal condition; applying a metal powder to the radial surface free from the deteriorated metal condition to yield an ultrasonic rotary horn having a radial surface free from deteriorated metal condition and with metal powder thereon; and hot isostatically pressing the ultrasonic rotary horn having the radial surface free from deteriorated metal condition and with metal powder thereon to consolidate the metal powder and fuse the metal powder to the radial surface to yield a repaired radial energy transfer surface comprising consolidated metal fused to the radial surface free from the deteriorated metal condition.
