摘要：

The change in the corrosion behavior of amorphous Fe-10Cr-13P-7C and Fe-4Cr-5W-13P-7C alloys by the annealing-induced structural relaxation was investigated in 1 M HCl. The structural relaxation led to an increase in active dissolution current density by the introduction of chemical heterogeneity in the alloys. The passive current density of amorphous Fe-10Cr-13P-7C alloy was not affected by annealing, while the annealed amorphous Fe-4Cr-5W-13P-7C alloy revealed a higher current density than as-quenched counterpart at low potentials in the passive region, where the current density decreases with increase in alloy tungsten content. © 1990.
