Abstract
wt%, corrosion by dissolution at a rather high rate was dominant, and the corrosion depth was as high as 50 μm for 100 h. It is speculated that the oxide layer is also formed at the initial stage but gets dissociated when there is no oxygen supply to sustain the oxide layer with prolonged exposure time. The oxygen content in the cover gas greatly influences the corrosion behavior of 316SS, thus directly affecting the application of 316SS immersed in liquid lead at high temperature.
