Characterisation of the surface microstructure of a melt-spun Ni-Ti shape memory ribbon

Jenko, Monika, metalurginja ...

Because of their unique mechanical properties, shape memory and super plasticity, durability and biocompatibility, Ni-Ti alloys are the most important memory shape alloys for applications in a wide ... range of medical implants and devices. These alloys contain approximately equal Ni and Ti atomic concentrations, meaning medical applications are still hindered by the concern for the release of Ni into surrounding tissues. We have studied the surface composition of a melt-spun Ni-Ti shape memory alloy using different surface analytical techniques, namely, Auger electron spectroscopy and X-ray photoelectron spectroscopy, before and after testing its biocompatibility in vitro. We have found that the surface consists of an oxide layer of 10 to 20nm thickness, composed of Ti oxide and some Ni oxide with metallic Ni inhomogeneously distributed in the subsurface region.
