Impedance Data

Bare silicon and 20% yttria stabilized ceria on a silicon substrate are annealed. The annealed substrates are analyzed at varying temperatures using electrochemical impedance spectroscopy. The impedance data is fitted against appropriate equivalent circuits and the fitted data is characterized with an Arrhenius plot and a plot of the ionic conductivity against temperature. The 20% YDC sample is found to have a high ionic conductivity, and therefore should be studied further in order to determine the practicality of using YDC as an electrolyte.

The paper is an electrochemical study regarding the influence of different acid etching conditions on the corrosion behaviour of a new Ti based bioalloy with Nb, Ta and Zr. Open circuit, potentiodynamic and electrochemical impedance spectroscopy were the methods performed in a simulated body fluid (SBF) and a stability mechanism was discussed in terms of equivalent circuits.
