**3. Conclusions**

Failure Analysis of Biometals presents a collection of studies covering a wide range of failure mechanisms in medical implant materials. The contributions reflect the profound interest in this area aiming to address current issues in biometals, manufacturing techniques, and implant applications, while employing various research methodologies. Challenges still remain, however, there are also grea<sup>t</sup> opportunities for research to better analyse and understand failures in biometals and come up with successful engineering solutions.
