Abstract

To ensure adequate wear resistance on some of the nuclear reactor components made of Zircaloy-2, a uniform thick buff oxide layer is desirable. Commonly used methods to evaluate oxide thickness (i.e., metallography and weight gain) have certain limitations. In this paper, results of eddy current (ECT) monitoring as a function of oxide layer thickness (determined metallographically) on Zircaloy-2 surface have been reported. A linear correlation between ECT response and oxide layer thickness has been established.
