description: Theme of qualification work: "Synthesis of titanium nickelide by mechanical alloying and plasma spheroidization methods, suitable for use in additive technologies". This work is devoted to the development of a method for obtaining spherical titanium nickelide powder by mechanical alloying and plasma spheroidization, suitable for use in a selective laser melting unit for the manufacture of coronary stents. Tasks of the final qualifying work: - analysis of scientific and technical information about titanium nickelide, methods of its production and application; stents and methods of their manufacture; technologies of mechanical alloying, plasma spheroidization and selective laser melting; - carrying out experimental studies of the production of titanium nickelide powder by mechanical alloying and analysis of its properties; - obtaining a powder of a spherical shape by the method of plasma spheroidization and analysis of the resulting powder; - modeling of the shape of the stent using computer-aided design systems; - manufacture of a stent by selective laser fusion and analysis of the properties of the resulting product. For the manufacture of stents from titanium nickelide, the initial content of nickel and titanium was chosen to be 50.7 and 49.3 (at %), respectively. In next step, the fragmented titanium nickelide powder obtained by mechanical alloying was analyzed for particle size distribution, particle chemical distribution, and phase composition. Also, the main technological problem was obtaining a powder with a low oxygen content. For this reason, work was carried out to reduce it and a gas analysis was made. Next, the mode of plasma spheroidization was selected and the study of the obtained morphology and particle size distribution of titanium nickelide powder was carried out. Also, differential scanning calorimetry of the obtained material was carried out to reveal the shape memory effect. The next stage of work was the design of the stent model and its further printing using selective laser fusion. A suitable mode was selected and the properties of the resulting product were analyzed.
