Abstract

Anodic behavior of amorphous Fe40Ni40B (20-X)PX alloys with X ranging from 0 up 20, in buffered solutions, pH ranging from 4.0 up to 8.4, is reported. Electrochemical measurements give evidence, that P improves ability to passivate and stability of the passive state of these alloys; the effect not attributable to a specific Cr-P interaction in this case. Data concerning chemical state of passive film constituents, in particular of these containing P, are analyzed. A possible mechanism of P action is discussed.
