ABSTRACT:
The present invention relates to cemented carbide bodies preferably for rock drilling and mineral cutting. By having the bodies comprising a core of cemented carbide containing eta-phase surrounded by a surface zone of cemented carbide free of eta-phase and having a low content of cobalt in the surface and a higher content of cobalt next to the eta-phase zone the bodies have obtained an increased strength and life in practical use.
