A Review Study on Biocompatible Improvements of NiTi-based Shape Memory Alloys

NiTi-based shape memory alloys (SMAs) have many applications, especially for implantation, however since they are not a passive material so it is important to investigate them from different biocompatible perspectives. In this study, we introduced the physical characteristics of NiTi alloys, then explained terminologies, including carcinogenic, genotoxic, cytotoxicity, mutagenic, allergic, and corrosivity. We collected some previous works that investigated biocompatibility SMAs techniques used improving alloy diminishing hazard due Ni-leakages.
