✦ Synopsis

Analyses of the responses of anodically filmed Nb electrodes to a square current wave have been made down to times -10 ns and show a characteristic single relaxation time.

Cathodic polarisation of filmed electrodes results in a second relaxation process associated with an increase in the measured capacitance. These changes are reversible and associated with changes in the bulk properties of the surface oxide layer.

Changes in the thermal oxidation of zirconium due to the presence of an initial electrolyticallyformed oxide layer are studied. The increase in thickness of the oxide on heating is measured optically and gravimetrically. The effect of the initial layer is the same as if it had been produced thermall
