| Abstract: |
| Because of the excellent mechanical properties and biocompatibility, titanium (Ti) alloy has been widely used as orthopedic implants in clinical. However, as a bioinert material, aseptic loosening of Ti alloy implants always takes place after surgery due to the lack of osseointegration ability, and infection caused by bacteria is always unavoidable. Therefore, the bioactivity of Ti alloy needs to be further improved. Magnesium (Mg)-based metal is biodegradable. The alkaline environment generated through degradation process and the metal ions such as Mg2+ release have multiple biological activities which is beneficial to bone tissue reconstruction, such as antibacterial properties, osseointegration and vascularization. Nevertheless, the strength of Mg is relatively low, and it cannot be applied to load bearing position of human body. Therefore, the work aims to fabricate Mg coating on Ti alloy and combine the advantage of mechanical properties for Ti alloy and biological activity for Mg coating, providing a potential alternative choice for bone implant materials. |
