Paper Title:
Corrosion Behaviors of Ultrapure Ferritic Stainless Steels in Simulated Urban Refuse Leachate
  Abstract

The corrosion behaviors of ultrapure ferritic stainless steels in simulated urban refuse leachate were investigated by means of different measurement methods including steady-state polarization curves, potentiostatic open-circuit relaxation curves and scanning electronic microscope. The results show that the ultrapure ferritic stainless steel 443, 444 and the austentic stainless steel 304 maintained good passive state after being immersed in the simulated leachate for 720h. The descending order of pitting resistance is 444>443>304. According to the passive film equivalent resistance Rp and the interface capacitance Cd obtained by fitting the potentiostatic open-circuit relaxation curves, the descending order of passive film stability is also 444>443>304.
