Surface hardening method of spring such as plate spring, involves using ultrasonic balls that are accelerated by sonotrode for radiating ultrasonic waves onto underside, inner side and outer side of spring

The method involves using ultrasonic balls that are accelerated by sonotrode for radiating ultrasonic waves onto underside, inner side and outer side of a spring. The surface area of the spring is borated and/or nitrated. Die vorliegende Erfindung betrifft ein Verfahren zur Oberflächenverfestigung b...

Beschreibung
Zusammenfassung:	The method involves using ultrasonic balls that are accelerated by sonotrode for radiating ultrasonic waves onto underside, inner side and outer side of a spring. The surface area of the spring is borated and/or nitrated. Die vorliegende Erfindung betrifft ein Verfahren zur Oberflächenverfestigung bei einer Feder, insbesondere bei einer Teller- oder einer Wellfeder. Erfindungswesentlich ist dabei, dass eine Oberfläche der Feder zumindest bereichsweise Ultraschall-Kugelgestrahlt wird.
