| Abstract: |
| Titanium and its alloys have become the most commonly used metal materials in the medical field due to their good corrosion resistance, biological activity, biocompatibility and non-toxicity in physiological environments. However, titanium and its alloys are easily polluted by environment and wore out during long-term service due to lack of antibacterial properties, high friction factor and low resistance to plastic shear, which limits the expansion of their application to a certain extent. Therefore, some scholars often apply ion implantation technology to modify the surface of titanium and its alloys in order to improve the surface performance and extend the service life of their parts and expand their application range. Studies have shown that a single element ion implantation is insufficient to improve the medical performance of titanium and its alloys, so some scholars use multiple implantation technology with metal + non-metal or metal + metal ions, aiming to improve the anti-friction and anti-wear properties, and the corrosion resistance of the modified layer, as well as enhance the biological activity and the antibacterial properties during service. In addition, after the existing researches were analyzed and reviewed, the development trend on medical titanium and its alloys modified by ion implantation was proposed for further in-depth theoretical and simulation research, multiple ions (especially metal + metal + non-metal multiple ions) implantation research, the development of a high-performance ion implantation equipment and formulation and optimization of its ion implantation parameters. |
