摘要：

The pitting resistance of Fe-Cr and Fe-Cr-Mo alloys has been correlated with characteristics of the passive films analyzed by Auger electron spectroscopy (AES). Increased film protectiveness as a result of increased Cr is attributed to Cr enrichment of the film and decreased film thickness. Increased Mo or passivation at noble potentials promotes passive film resistance to breakdown, but it is suggested that the roles of alloying and/or passivation conditions are related to weak points of the film.
