摘要

The role of thiosulfates in pitting induced by chlorides on Fe-17Cr alloys in neutral medium was investigated by electrochemical and XPS techniques. The concentration was 30 ppm S_2O_3~2- in 0.02 M NaCl. The studied alloys contained different contents and kinds of sulfide inclusions (Ti or Mn sulfides). Electrochemical experiments (I-E curves and pitting probability measurements) show the deleterious effect of thiosulfate addition. The detrimental effect of the thiosulfates on the pitting resistance increases with increasing sulfur content in the Alloy.
