The results of a research on the surface morphology of nanostructured nickel after high-fluence irradiation with 30 keV argon ions have been presented. The nanostructure in nickel was formed by high-pressure torsion deformation. It has been shown that deformation nanostructuring of nickel and subsequent ion-beam sputtering allows receiving a surface uniformly coated with submicron cones. The thermal stability of the obtained cone-shaped structure on nanostructured nickel has been determined. Keywords: nanostructure, high-pressure torsion, ion irradiation, cones, thermal stability. |
