| Abstract: | While the Ti-6Al-4V alloy is widely preferred for orthopaedic implants, it is crucial to address the potential risks of genotoxicity and implant loosening caused by released metal ions and the absence of osseointegration, respectively. In this context, the present invention describes novel borosilicate based bioactive glass compositions, suitable for coating application on Ti-6Al-4V implants. The assessed characteristics of these glasses demonstrate high thermal stability (145?C), fast in vitro bioactivity(24-72h) and similar linear thermal expansion coefficient (8.5-12.19? 10-6/?C) to that of the alloy. The favorable combination of properties enables achievement of a well adherent and amorphous coating on the alloy surface, ensuring osseointegration capability and protection against the risk of genotoxicity. Additionally, this invention presents a commercially viable coating technique that involves cold-spraying followed by thermal treatment, resulting in desired amorphous coating on the implant surface. Overall, this invention is anticipated to greatly enhance the performance of Ti-6Al-4V based orthopaedic implants. |
