摘要：

Heat treated in different ways, Zr-Sn-Nb zirconium alloy specimens were exposed to 0.01 mol/L LiOH aqueous solution at 350°, 16.8 MPa. The examinations of the oxide film microstructures of the specimens subjected to different corrosion time were carried out by using X-Ray Diffraction (XRD). The results show, the longer the corrosion time, the faster the corrosion rate, the less the tetragonal zirconia (t-ZrO2) content in oxide film. The conclusion is: the high content of t-ZrO2 will improve the protection of the oxide film.
