Description

The hardening effect on the surface layers of WC-Co alloys after Ar+- and N+-ion implantation with the fluence in the range 1 divided by 8.7 x 1017 cm-2 has been investigated at room temperature and under heating with an ion beam. The depth of the Auger distribution profiles and the microhardness of implanted samples were measured. The radiation-stimulated diffusion of nitrogen atoms and the microhardness enhancement were observed. The contribution of the polymorphic Co-phase transformation and the production of Co-N compounds is discussed. (author)
