Abstract

The effects of adsorbates on the oxidation of Zircaloy-4 in air and steam are studied by the measurement of the weight gain of specimens. The effect of LiOH is dependent on surface condition, temperature and type of atmosphere. LiOH works as a mineralizer stabilizing monoclinic phases. LiOH only affects the specimens of pickled surface. LiOH enhances oxidation at low temperature, but retard oxidation at high temperature. NaCl enhances the oxidation, where nonuniform stresses on the surface and embrittlement of oxide by Cl are the cause. The effects of fluorides on oxidation are also measured. NaF is most harmful and KF follows next. LiF does not effect the oxidation of Zry.
