Influence of fabrication conditions on the morphology and electrochemical properties of bulk and tape amorphous Fe55Ni20.8Cr7.04Mo1.61V1.07B6.56C2.67P4.7Si1.07 alloy in aggressive mediums with various pH is investigated. On the surface of bulk alloys during hardening at lower cooling rates than during fabrication of tape samples, different (‘dark’ and ‘light’) phases enriched with Fe and Co are formed. New phases can be formed from reactionary atoms that leads after active dissolution to passivation of the bulk sample surface. Tape sample has higher corrosion resistance in 0.5 M aqueous solutions of NaCl, HCl and KOH as compared with bulk sample of similar composition. As shown, the tape and bulk samples with such composition are more resistant in 0.5 M HCl aqueous solution.
