Abstract

The parameters that must be known if the extent of damage due to the crevice corrosion of Grade-2 titanium waste containers is to be predicted are discussed. These parameters include the kinetics of crevice propagation as a function of temperature and oxygen concentration, the critical values of temperature and oxygen concentration for which repassivation occurs, the rate of hydrogen absorption by the metal under crevice corrosion conditions, and the threshold value of absorbed hydrogen concentration above which the material may be susceptible to hydrogen-induced cracking. The results of experiments to measure these parameters are briefly summarized, and their significance as modelling parameters or criteria are discussed.
