摘要：

Cyclic polarization and pit propagation rate tests were performed on FeNiCrMo alloys having Mo concentrations of 3, 6 and 9 weight percent for three Fe/Ni ratios. The critical current and pit current densities were found to be dependent on a coupled NiMo dissolution mechanism at low Fe contents. At high Fe concentrations, Fe governed the dissolution process. © 1990.
