description: This work is devoted to the study of the possibilities of obtaining NiTi compounds for the manufacture of coronary stents using mechanical alloying, as well as to the search for optimal modes for this treatment. Tasks that were solved during the study:
1. The study of the requirements for coronary stents, the study of their types, materials and methods with which they are made;
2. The selection of the most promising materials, as well as the study of alternative methods for their preparation;
3. Development of a technology for producing a homogeneous powder of the required chemical composition using mechanical alloying technology.
4. The choice of the optimal regime of mechanical alloying according to the results and conclusions.
The work was carried out at the Peter the Great St. Petersburg Polytechnic University in the Russian-Chinese research laboratory "Functional Materials", where work was carried out on attritors for the process of mechanical alloying. The experimental results were analyzed, which allowed us to choose the optimal processing mode. Based on the results, conclusions were drawn and research
objectives formed.
