摘要

The effect of chromium content in Ni(bal.)-Cr(16,19,22,25,30)%-9%Fe alloys on corrosion behaviors in PWR primary coolant was investigated in this work.Corrosion test was carried out in simulating PWR primary water at 330℃.Corrosion rate decreased parabolically with the increase of Cr content and showed the similar value for the Ni-Cr-Fe alloys including the Cr content more than 22 wt.%.
