This thesis explores the corrosion behaviour of titanium under physiological conditions, particularly under conditions resembling the oral cavity. The motivation for this study is a novel explanation technique for dental implants. This technique involves the application of high-frequency current to the implant. Application of this procedure leads to a reversal of the integration of the implant into the bone. This technique can considerably reduce trauma and damage to the bone and tissue. The application of current to the implant leads to questions concerning titanium's corrosion behaviour, which must be addressed. Different types of titanium samples have been produced and tested for their corrosion behaviour in artificial body fluids. For this purpose, techniques including Cyclic Voltammetry, Chronoamperometry, Impedance Spectroscopy and Electrochemical Noise measurements have been performed. In addition, techniques for surface modification of titanium samples were explored. An electrochemical flow cell was designed and built. This cell is capable of being operated in combination with an ICP-OES for electrolyte analysis. The operational capability of the cell was tested, and measurements in combination with an ICP-OES were performed. It was possible to determine the corrosion behaviour of titanium under simulated physiological conditions. Further, the influence of H2O2 on the corrosion behaviour was quantified. Electrochemical noise measurements were successfully used to compare certain corrosion parameters of titanium under different conditions. Despite proving suitable to study corrosion parameters, this technique still holds limitations and challenges to produce results which are comparable to in a standardized manner. While the working capability of the flow cell was successfully demonstrated, the ICP-OES in its current setup (end on plasma) proved to be insufficient to quantities the titanium content of the electrolytes.
