Abstract

An apparatus is described for determining the corrosion behaviour of rotating (≤ 2 Hz) metal specimens in test solutions having a range of dissolved oxygen concentrations. Long term tests (up to 150 days) have been carried out on steel specimens at temperatures between 5 and 90°C in triply distilled water, solutions containing 35 ppm Cl^-, Teddington tap water, and sea water. Oxygen concentrations ranged from near deaerated (∼ 0·08 ppm O₂) to oxygen saturated. Increased chloride and oxygen content increased the mass loss of the specimens during the test period, although a high concentration of oxygen in the absence of chloride ions passivated the surface of the steel. Hardness salts decreased the mass loss of the specimens.
