| Abstract Thin ribbons of amorphous Fe_(75)Cr_5P_(13)C_7 alloy were prepared by single-roll rapid-quenching method. The composition, structure and mechanical property of the samples were analysed. Corrosion behaviour of the alloy in 1N H_2SO_4, 1N H_2SO_4+0.5N NaCl, 1N HCl and 10% FeCl_3��6H_2O solutions was investigated by means of the method of complete immersion and the curves experimentally determined of potentiodynamic polarization and of potentiostatic current density vs. time. The results indicate that the property of the amorphous alloy prepared by the simple method mentioned is stable. It is exceedingly corrosion-resistant in acid mediums. Its corrosion behaviour was not significantly affected and it did not suffer pitting when the medium contained Cl~- ions, The high resistance to corrosion of the amorphous alloy might be the result of that there are no crystalline defects such as grain boundaries, dislocation faults, segregation etc, in it, and that it has extremely high reactiyity with rapid formation of passive film. |
