Biocorrosion and cytocompatibility assessment of NiTi shape memory alloys

Ti-based alloys are characterised by an excellent corrosion resistance, high mechanical performances, an increased biocompatibility, and in particular by the deforming force of NiTi. Five alloys were examined by electrochemical assays and cell culture tests with different cell types. All tests show...

Description
Summary:Ti-based alloys are characterised by an excellent corrosion resistance, high mechanical performances, an increased biocompatibility, and in particular by the deforming force of NiTi. Five alloys were examined by electrochemical assays and cell culture tests with different cell types. All tests show the high biological and electrochemical performances of Ti6Al4V and NiTi, and in particular a significant influence of living cells on corrosion.
