Investigations on metal depositions and dissolutions with an improved EQCMB based on quartz crystal impedance measurements

With the experimental set-up frequency and damping changes of resonating quartz crystals in electrochemical experiments can be measured at a time resolution of about 500 ms. The damping effects accompanying metal depositions and dissolutions (Ag and Cu) on polycrystalline Au electrodes of 6 and 10 MHz AT quartzes were studied and discussed in terms of roughness and sliding effects.
