Abstract
The present invention relates to a method of surface hardening a plurality of sintered bodies having a hard phase and a binder phase. The method includes the steps of placing the bodies in a container, and forming a system including the container and the bodies therein, and causing the bodies to move and collide with each other and with inside walls of the container. The container is vibrating utilizing a mechanical resonance frequency of the system.
