THE INFLUENCE OF VARIOUS IONS ON THE RATE OF CORROSION OF 18% Cr, 13% Ni, Nb STABILISED AUSTENITIC STEEL IN 70% W/W NITRIC ACID
The influence of certain ions containing cerium, vanadium, reolybdenum, and thorium on the rate of corrosion in nitric acid of 18% cr, 13% Ni, niobium stabilized austenitic steel has been determined. The results, together with those obtained previously in this investigation, are reviewed, and an explaration is advanced to account for the observed differences in the extent to which different ions accelerate corrosion. It is suggested that the mechanism of accelerated corrosion is governed by cathodic depolarization, and the effect of different ions is discussed in terms of the redox potentials of the probable reactions involved at the cathodes. The role played by nitric acid is also discussed. (auth)
