Effect of surface treatment on the biological compatibility of NiTi shape memory alloy / 国际生物医学工程杂志

Nickel titanium shape memory alloys(NiTi-SMA) are thought to be the promising biomaterials of biological osteosynthesis(BO) with regard to biomedical applications. However, a critical concern is the release of harmful Ni ions from the implants into the living tissues. And little is known about the influences of surface modifications on the biocompatibility of these alloys. The emphasis was focused on the recent developments, the related questions, surface treatments, future directionsin.
