| Summary: | Title screen Studies were conducted on the phase and chemical composition, electrochemical properties, and superelastic behavior of a Ti2Ni-rich near-equiatomic TiNi alloy exhibiting different surface treatments (electropolishing, irradiation with a low-energy high-current electron beam, high-dose ion implantation). The thickness of the oxygen-rich surface layer in the irradiated samples was found to be twice that of the electropolished alloy. Additionally, ZrO₂ and Ni-Zr phases formed in the upper surface layer after Zr⁺ ion implantation. Tafel extrapolation results showed that the electropolished alloy exhibited the lowest corrosion current. Electrochemical impedance spectroscopy highlights the advantages of electron-beam treatment in improving the self-passivation ability of the TiNi alloy. Evaluation of the superelastic behavior showed that neither electron beam nor ion beam surface treatments negatively affect the superelastic properties of the TiNi substrate, but rather promote a decrease in plastic deformation Текстовый файл AM_Agreement |
