Project abstract
The project is aimed at the development of a combined processing method for the spherical head of a hip implant, including Ultrasonic Nanocrystal Surface Modification, ion-plasma nitriding and multilayer coating application by magnetron sputtering. This method makes it possible to obtain a coating with a multilayer architecture consisting of a nanocrystalline layer, a nitrided nanocrystalline layer, and a multilayer Ti/TiN coating. By selecting the optimum regime of workovers, a gradient distribution of microstructure, residual stress and microhardness over thickness will be ensured. This project will study the antibacterial, toxicity, mechanical, corrosion, tribological and tribocorrosion characteristics of the obtained multilayer coating. The effect of preliminary ultrasonic modification of the substrate surface on the structural-phase states, hardness, wear resistance, thickness of the nitrided layer, as well as on the adhesion strength of Ti/TiN coatings will also be studied. It is proposed to comprehensively study the biocorrosion behavior of multilayer Ti/TiN coatings under in vitro conditions.
The research results will be important from the point of view of scientific research in the field of condensed matter physics and materials science, as well as from the point of view of practical use in the creation of medical implants. The results of the research can be implemented into production created on the basis of VKTU named after. D. Serikbaeva (Applicant). The implementation of the results of this project ensures the competitiveness of domestic implants. Thus, the results of the research will contribute to the development of medical sciences in the Republic of Kazakhstan. At the same time, the project is of great significance on a national and international scale. Thus, in recent years, developments aimed at improving hip implants have attracted increasing attention.
Project goal
Development of a combined processing method for the spherical head of a titanium alloy hip implant, which will improve its tribological, mechanical, and corrosion characteristics.
Expected and achieved results of the project:
| Year | The results obtained from the research. Publications (with links to them) and patents; information for potential users. |
|---|---|
| 2023 | Determined optimal mode of ultrasonic modification of the surface of titanium alloy Ti-6Al-4V. Experimental determination of optimal ion-plasma nitration mode of titanium alloy Ti-6Al-4V. |
| 2024 | The main mechanisms of formation of the nitrogenated layer on the surface of the ultra-soft grain alloy Ti-6Al-4V have been identified. The role of ultrasonic surface modification and nitrogenation in ensuring adhesion strength of Ti/TiN multi-layer coating has been determined experimentally. The mechanical and tribological characteristics of Ti/TiN multi-layer coatings will be determined depending on the thickness and number of beams. |
| 2025 | Corrosion and antibacterial characteristics of Ti/TiN multi-layer coatings will be studied depending on the spraying modes. The toxicity of Ti/TiN coatings will be studied. The characteristics of surface degradation of Ti/TiN coatings with combined exposure to corrosion and wear in the biological environment will be studied. |
