Abstract
The electrochemical behavior of tungsten in I NI H2SO4 and KOH solutio ns is studied by the contact electric resistance (CER) method, which e nables one to detect the adsorption and phase oxide films on the elect rode surface. Time variation of CER Is measured at given potentials in the anodic and cathodic regions. CER for the W/KOH electrochemical sy stem, polarized with bipolar rectangular potential pulses, is measured as a function of the amplitude and length of the pulses.
