By the methods of chronopotentiometry, voltammetry, and scanning electron microscopy, we investigate the influence of modification of the Fe78.5Ni1.0Mo0.5Si6.0B14.0 and Fe73.1Cu1.0Nb3.0Si15.5B7.4 amorphous metallic alloys by heat treatment (373 and 473°K), holding in variable magnetic fields (50 Hz), and combined thermal and magnetic treatment of different durations on the corrosion rate of the surface of amorphous metallic alloys in a reference NaCl solution. It is shown that we can substantially increase the corrosion resistance of alloys using by applying variable magnetic fields for 3 h in the case of Fe78.5Ni1.0Mo0.5Si6.0B14.0 alloy and for 3 h with subsequent annealing at 473°K for 1 h in the case of Fe73.1Cu1.0Nb3.0Si15.5B7.4 alloy.
