The article shows the influence of ion implantation of nitrogen and electron-beam processing on structural-phase state and microhardness of a dispersion-hardening 67CoNi5Nb alloy. It is established that at the surface treatment of electronic and ion beams is the place to morphological changes, and changes in the elemental composition of the 67CoNi5Nb alloy. It is determined that in the result of treatment by nitrogen ions and electrons on the surface of a dispersion-hardening 67CoNi5Nb alloy formed fine inclusion due to surface segregation of niobium. It is shown that the
ion implantation leads to an increase in the microhardness to 10–50%, depending from dose of irradiation. It is determined that the surface microhardness of the 67CoNi5Nb alloy after electron irradiation increases almost to 2 times.
