Abstract
The hardening effect on the surface layers of WC-Go alloys after Ar+- and N+-ion implantation with the fluence in the range 1 divided by 8.7 x 10(17) cm(-2) has been investigated at room temperature and under h eating with an ion beam. The depth of the Anger distribution profiles and the microhardness of implanted samples were measured. The radiatio n-stimulated diffusion of nitrogen atoms and the microhardness enhance ment were observed. The contribution of the polymorphic Go-phase trans formation and the production of Co-N compounds is discussed.
