Abstract
The suitability of electrochemical noise measurements to gather information on the corrosion behavior of titanium implants is explored. Rod-shaped titanium samples have been immersed in different types of electrolytes, and the generated electrochemical noise is evaluated. The electrolytes include simulated body fluids, namely phosphate-buffered saline and artificial saliva. Different data evaluation methods have been explored. The evaluation of the time-domain data and further statistical methods shows promising results. Noise resistance values ranging from 0.09 MΩ for 3.5 wt% H2SO4 solution up to 0.45 MΩ for simulated body fluids have been recorded. It is possible to determine the dominating corrosion modes on the sample surface and reach results in alignment with expectations and established knowledge on corrosion mechanisms.
