“…In the remained cases, elements' concentration in solutions increases (Figures 15 and 16) over time, but leaching of elements in medium considerably slows down. It can be related to sequential processes of the destruction and renewal of the protective film (de-and repassivation) on defect areas [30,31].…”

“…In solution with Ti-TiNi (Figure 15a), titanium concentration is approximately twice more than nickel that is explained by chemical interaction of surface layer material with potassium tetraoxalate [31]. In case of composite material with a tantalum surface layer, Tа concentration was also considered (Figure 15b).…”

“…Depending on material treatment (Figure 16), ion release decreases in the following order: TiNi-2 > TiNi-1 > TiNi-4 > TiNi-3 > Ti-TiNi (if to look on nickel concentration) > Та-TiNi. According to the literature, the thermal treatment at a temperature from 400 to 1000°C, which is required for stabilization of the mechanical properties, always results in a significant worsening of the corrosion resistance [31]. At the same time, the surface treatment, which facilitates the formation of the most perfect and homogeneous passive film, increases the corrosion resistance.…”

Biocompatible composites obtained using the magnetron sputtering for the production of minimally invasive implantation medical devices (stents) were investigated. Nano-and microdimensional surface layers of Ta, Ti, Ag, and Cu on flat and wire NiTi, Cu, Ti, and SiO 2 substrates were created. The phase composition, surface morphology, and the layer-by-layer composition were investigated on an X-ray diffractometer, SEM, and Auger spectrometer. It was shown that the thickness and the structure of surface layers were affected by the sputtering distance, time, power, and the bias voltage at the substrate. The presence of the transition layer that contains both substrate and target elements and provides high adhesion of the surface layer to the substrate has been demonstrated. The material was tested for corrosion resistance under static conditions by dipping into solutions with various acidities (pH from 1.68 to 9.18) for 2 years, static mechanical properties, and biocompatibility in vitro and in vivo. A slight corrosive dissolution was observed only in a medium with a pH of 1.56. Dissolution in the other media is absent. An increase in strength and plasticity in comparison with substrate was attained depending on the nature of the sputtered substance and substrate. Toxicity of samples has not been revealed.

“…Ti6Al4V alloy plays an important role for orthopaedic applications [21][22][23][24][25]. Nickel-titanium alloy (Nitinol, shape memory alloy) has been used in the treatment of cardiovascular implants [26][27][28][29][30]. The combination of the high corrosion resistance, the tensile strength, the flexibility, and the biocompatibility, is the reason of widespread and successful application of titianium and its alloys in modern implantology [31][32][33][34].…”

The research efforts in understanding the influence of TiO 2 1D nanoarchitecture structure and morphology on its biological and photocatalytic activity absorbed a lot of attention during last few years. Nowadays, the application of TiO 2 coatings in biomedical technologies (e.g., in modern implantology) requires the material of strictly defined structure and morphology, possessing both high biocompatibility, as well as antimicrobial properties. The presented review is a compilation of interdisciplinary knowledge about the application of 1D TiO 2 nanostructural coatings (nanotubes, nanofibres, nanowires) in biomedical technologies. The methods and parameters of their synthesis, and the physicochemical techniques used in the characterization of their structure and morphology, are discussed. Moreover, their ability to be applied as innovative coatings for modern implants is presented.

“…When such devices operating and installing in the body, less destruction of the implant itself and tissue damage are ensured [1][2][3]. These properties are best manifested in titanium nickelide, but the composition of this material includes toxic nickel that can influence surrounding tissues directly from the surface of the implant or be released into physiological environments as a result of corrosion, leading to both destruction of the product and to damage of the body [4][5][6][7][8][9][10][11][12][13]. At the same time, it is possible to develop nickel-free alloys with a shape memory effect and superelasticity.…”

Abstract. New shape memory alloy (Ti-20Nb-10Ta-5Zr) for production of minimally invasive implantation medical devices (cava filter) was tested for static mechanical properties. The material for investigations was wires with different thickness before and after thermal treatment in various conditions and surface mechanical treatment. The structure was investigated on a scanning electron microscope and on a Auger spectrometer. High indicators of strength and ductility were noted. The mechanical treatment of the surface and annealing in vacuum best affect it.
