Abstract

The electrochemical stability of Ni-Ti-O nanoporous layers anodically grown on the equiatomic NiTi alloy is assessed by immersion in deionized water and phosphate buffered saline and the influence of immersion on the corrosion behavior and biological properties is studied systematically. The morphology, chemical composition, and microstructure of the layers exhibit no obvious change even after immersion for 60 days in the two media and the corrosion resistance, antibacterial ability, and cytocompatibility are retained as well. These findings indicate the Ni–Ti–O nanoporous layers are stable and have large potential as coatings on NiTi biomedical implants.
