The elemental and phase composition, structural state, and mechanical properties of surface nickel layers modified by implantation of titanium ions using a Raduga-5 vacuum-arc ion and plasma source were investigated. An increase in the thickness of ion-implanted nickel layer from 0.6 to 1.6 μm with increasing ion-implantation dose from 0.8.1018 to 2.9.1018 cm-2 was observed. It was established that ion-implanted surface nickel layers contain fine-grained intermetallic phases NiTi, Ni3Ti, and NiTi2 and a solid solution of Ti in Ni. It was shown that the microhardness of surface nickel layers implanted with Ti ions exceeds that of the initial target material.
