Abstract—The effect of ion implantation on the surface morphology, structure of oxide layers, and electrochemical properties of nickel titanium TiNi in a 0.9 wt % sodium chloride (NaCl) solution has been studied. It has been established that the modification of the TiNi surface with titanium and niobium ions at an irradiation dose of 1017 ion/cm2 increases the surface roughness and improves the corrosion properties, which manifests itself in the growth of the charge transfer resistance and the drop of the anodic current. The comparative transmission electron microscopy analysis of the structure of the oxide layers and study of their electrochemical properties have shown that the corrosion properties of TiNi are caused by the complex phase composition of the surface. In particular, the niobium ion-beam treatment has resulted in the formation of a thin (~2 nm) continuous amorphous oxide film with a low permittivity (ε = 44) on the TiNi surface.
