Abstract

Abstract

Two types of N36 cladding tubes were exposed to 500℃,10.3MPa superheated steam for 500 hours.The characteristics of the second-phase particles and the oxide layer formed on N36 claddings were analyzed by scanning electronic microscope.The corrosion kinetics show that the nodular corrosion resistance of specimen A is better than that of specimen B.In anaphase of corrosion,it is shown the effect of size of SPPs on the weight gain of corrosion maybe greater than that on the hydrogen solubility.
