Determination of state-of-discharge of zinc-silver oxide button cells. II. Impedance measurements

Corrosion resistance of nickel in artificial sweat and synthetic seawater

“…The potentiostatic technique using a 10 mV potential step per minute, the potentiodynamic method with a 1 V/min linear sweep and the scratch test previously described [l] have been applied. In addition the ac impedance method has been employed with the equipment described earlier [3]. The polarization resistance has been measured by sweeping the potential 5 25 mV with respect to the corrosion potential at a scan rate of 1 mV/min.…”
