Surface modification of Nitinol by biocompatible passive films

Nitinol, near-equiatomic nickel-titanium alloy exhibits unique properties, shape memory effect and superelasticity, and is therefore of huge importance in biochemical engineering for medical applications. Metal implants, because of their irreplaceable mechanical properties, are built in different part of human body (as bone replacements, stents). These materials corrode in contact with aggressive body fluids. Knowledge and prediction of electrochemical processes is necessary for designing and optimizing biocompatible coatings on Nitinol, which is the main goal of this investigation. Electrochemical methods will be used not only for in vitro investigation of Nitinol reactivity, but also for the functionalization of its surface. Nitinol surface will be modified with biocompatible coatings (anodically formed passive films) and surface characterization of these films will be done by highly-sophisticated surface-analytical methods.
