Fig. 6

The corrosion rates of a all the insonified micro-sections of CS-5 and b all the insonified micro-sections of CS-6 (red ellipse: the transient surges and drops in corrosion rate). The temperature-compensated peak amplitudes of the first reflected wavepackets that were received at c six representative insonified micro-sections of CS-5 and d six representative insonified micro-sections of CS-6. The corrosion rates of c the six representative insonified micro-sections of CS-5 and d the six representative insonified micro-sections of CS-6. (Shaded areas: the transient surges in corrosion rate and the transient drops in signal amplitude.) e The XRD spectrum of the precipitates in the residual electrolyte solution of Experiment #6.
