Electrochemical Behaviour of Titanium Based Biomaterials in Artificial Saliva

Abstract:

In the last decade, new titanium alloys such as Ti6Al7Nb and Ti6Al7NbN have been developed in different areas of dentistry. It is known that mechanical/electrochemical interactions accelerate corrosion in implant alloys, and these interactions can be reduced by improving the modular component machining tolerances or by improving the corrosion resistance. The aim of this study was to compare the Ti6Al7Nb and Ti6Al7NbN alloys corrosion resistance in AFNOR artificial saliva. Due to the nitrogen diffusion, the Ti6Al7NbN alloy presents more pronounced grain structure than Ti6Al7Nb. In the electrochemical estimations the polarisation data were converted into instantaneous corrosion rate values (jcorr). The obtained passivation properties were comparable for both alloys. The EIS spectra were best fitted using an equivalent circuit (EC) which was consistent with the model of a two-layer structure for the passive film. The electrochemical and corrosion behaviour of Ti6Al7NbN increased the occurrence of the implant alloy’s electrochemical degradation.
