摘要：

Corrosion behaviors of 304L stainless steel in different pH value potassium permanganate solution were investigated using the gravimetric analysis method, scanning electron microscope (SEM), potentiodynamic polarization. Most of the corrosion products are on the surface of 304L stainless steel exposed in acid potassium permanganate (NP, pH=1.8). A minimum of corrosion products are on the surface of 304L stainless steel exposed in potassium permanganate (HP, pH=6.5). Corrosion products on the surface of 304L stainless steel exposed in alkalinity potassium permanganate (AP, pH=12.5) are in middle. All specimens through reduction cleaning process of nitric acid and ascorbic acid show metallic luster. And there is no obviously effect on micromorphology of 304L stainless steel exposed in NP, HP and AP solution. The corrosion density ic of 304L stainless steel in HP solution is less than that in NP and AP solution. The results have showed that the corrosion ability of NP and AP solution for 304L stainless steel is more vigorous than that of HP solution in the chemical decontamination process. © 2017, Editorial Board of Journal of Nuclear Power Engineering.
