the corrosion behavior of 1Cr18Ni9Ti steel in washing condition with different concentrations KMnO4 +10% HNO3 solution was studied. The results showed that 1Cr18Ni9Ti steel in the system occurred intergranular corrosion
and the surface roughness increased. Meanwhile
with the increase of the concentration of KMnO4
the corrosion rate rose. When the KMnO4 concentration was 0.5%
the corrosion rate was about 80 nm/h
and following phenomena were observed: the charge transfer resistance decreased
the metal corrosion resistance and the intergranular resistance reduced
the intergranular corrosion intensified
the interface capacitance increased
and the uniformity of metal surface topography decreased.
