Abstract
A cyclically stressed, hollow hydrogen sensor probe for evaluating the corrosion fatigue performance of corrosion inhibitors. A portion of the probe is contained in a jacket having an inlet and outlet for circulating a corrosive fluid containing an inhibitor over the outer surface of the probe. Corrosion at the outer surface of the probe produces hydrogen which permeates to the evacuated inner portion of the probe and produces a current reading in an ion pump in communication with the probe interior, which current reading is indicative of inhibitor performance.
