The object of the research is new processes of formation of a complex of properties of Zr-Ti-Nb alloys in final products obtained by additive methods with adaptive modeling for 3D printing, and creation of functional surfaces of biocompatible implants by anodic processing technologies. The purpose of the work: obtaining materials based on the Zr-Ti-Nb alloy and studying their properties. The main results of the work are: a review of the literature on existing alloys; the technology for obtaining Zr-Ti-Nb alloys was developed; obtained samples of materials based on the Zr-Ti-Nb alloy; a study of the properties of Zr-Ti-Nb alloy materials was carried out. Research results indicate that the chemical composition of the new Zr-Ti-Nb alloy does not contain harmful impurities, such as aluminum and vanadium, which are included in the VT-6 alloy widely used in medicine. The corrosion resistance of the alloy is quite high. X-ray phase analysis made it possible to determine the phase composition of the alloy. The strength and yield limits, values of longitudinal elongation and transverse narrowing for the Zr-Ti-Nb alloy were determined by mechanical research. It was established that the Zr-Ti-Nb alloy has significantly higher plasticity compared to the widely known VT-6 alloy. It should be especially noted that the modulus of elasticity of the Zr-Ti-Nb alloy is 26.4 GPa, as well as the modulus of elasticity of cortical bone (equal to 15-30 GPa), unlike VT-6, the modulus of elasticity of which is 115 GPa. The obtained data allow recommending the Zr-Ti-Nb alloy for medical use. Field of application: M 72.19 Research and experimental development in other natural and technical sciences.
