It was shown, that the studied AMA in 0,06% solution as well as 3% NaCl solutions considerably higher corrosive stability comparability with the unalloyed alloys of the system Fe - Si - B. It is educed for slopes of voltammetric curves, which speed of corrosion of AMA depends on element composition and structural state of AMA, which changes as a result of annealing. For AMA НВ-1 the highest corrosive resistance in 0,06 % NaCl solution is observed. Practically identical corrosive properties the alloys B-12, НВ-2, НВСУ-1, НВСУ-2 in the aggressive solution of 3% NaCl are owned. Annealing of the AMA at 700 С during 0,5 hour results in structural changes in samples and in accordance with the change of corrosive properties. Most stable in 3 % natrium chloride solution is AMA НВСУ-1. The charge transfer resistance through interface AMA / NaCl solution by of the electrochemical impedance spectroscopy method was investigation. It was indicated, that annealing at 700о С lead to levelling of the influence frequency in the interval 100....10 000 Hertz. It is represented on smoothing of the values of charge transfer resistance of all alloys which limits of 11...16 kOhm. However, most corrosion resistant as a result of annealing and frequency influence is AMA B-15 (Fe95Cr5) 85B15, for it the charge transfer resistance equals 53,4 Ohm.
