Sažetak
Having in mind a need to extend the quality of life there is an ever-expanding requirement for implantation of metal implants in human body because of their superior properties. Nitinol, nickel-titanium alloy with near-equiatomic composition, derives its attractiveness and widespread use in biochemical engineering from unique mechanical properties known as shape memory effect and superelasticity. In spite of its good corrosion resistance due to the spontaneous passivation, it is of huge importance to prevent the unwanted release of toxic nickel ions. Hence, Nitinol surface was modified by biocompatible organic self-assembled monolayers and inorganic films (anodically formed passive films) in order to prevent release of nickel. In vitro characterization of modified and unmodified surfaces of Nitinol was performed in simulated body fluid (Hank’s solution) using electrochemical ac and dc methods. Surface films will be characterized by electronic microscopy and spectroscopic methods.
