Corrosion and wear-corrosion behavior of NiTi modified by plasma source ion implantation

Biomaterials.-Num 24 (2003)- pp 3931–3939. The understanding of corrosion behavior in NiTi is critical for the devices using this shape-memory alloy. In order to improve the surface properties of NiTi such as corrosion resistance, plasma source ion implantation (PSII) technique was employed with oxygen as incident ions at three levels of implantation dose.
