Growth Behavior of Murine Fibroblast Cell on Amorphous/Nanocrystalline TiNi

摘要

TiNi with superior shape memory and superelastic properties have been used widely in medical device applications due to its good biocompatibility. However, due to demand on implant type application for extended period of time, the corrosion properties and biocompatibility of TiNi need to be further improved. High pressure torsion technique in which materials are exerted with high compressive force and concurrent torsion straining allows for obtaining nanostructured materials with improved mechanical properties. In present study, the effect of HPT rotation on hardness and cytocompatibility was investigated for TiNi.
