Abstract

Slow strain rate test-Contact electric resistance (SSRT-CER) and impedance measurements of oxide films on stainless steels in oxygenated high temperature water were discussed. The CER measurements show that the oxide film resistance increased as the temperature was increased from room temperature to 288°C showing the growth of oxide films. In the initial stages, the resistance on the stressed part showed a peak, higher than that of the unstressed part. It was found that the films on the stressed parts are relatively enriched with chromium than on the unstressed part.
