THE INFLUENCE OF CONTAMINATING IONS ON THE CORROSION OF AUSTENITIC CHROMIUM- NICKEL STEELS IN NITRIC ACID. A REVIEW OF PROGRESS TO 1/9/52

Technical Report ·
OSTI ID:4212107
Since the discovery that chromate ions accelerated the corrosion of 18/ 13/1 steel in boiling 70% nitric acid, the effect of other ions has been investigated in an endeavor to elucidate the mechanism of acceleration. It has been found that vanadate, permanganate, and molybdate anions accelerate corrosioO as also does the ceric cation. Neither cobalt nor tungstate ions has a noticeable effect. These tests are now being repeated in a mere quantitative manner. At the same time, an attempt is being made to measure the effect of foreign ions on the solution potential of 18/13/1 steel in nitric acid. It is believed that an apparatus devised by Holler may enable this to be done. (auth)
