Pereverzieva T. Modification of surface of the amorphous metallic alloys based on Ferrum

Investigated and specified conditions of oxidation processes doped amorphous alloys group Fe-Si-B-(Me) in 0,5 M standard aqueous solutions of NaCl, HCl and KOH. Found that the previous temperature treatment at T = 77 K AMA samples does not cause changes in the structure and elemental composition of the surface, but reduces their dissolution in 0,5 M aqueous solutions of HCl and KOH. High-temperature modification at T = 673 K cause nanocrystallization of samples and formation in amorphous phase crystals of Fe3B size of 20-30 nm, resulting in activating of alloys surface. Modification with alternating magnetic field leads to inhibition of dissolution processes of AMA Fe78,5Ni1,0Mo0,5Si6,0B14,0 in 0,5 M aqueous solution of NaCl, in case of alloy Fe73,1Cu1,0Nb3,0Si15,5B7,4 impact of alternating magnetic field graded. After such modifications multicomponent alloy Fe59Ni26Cr6,6Mo0,9V1,6W0,3Si3B2,9 proved to be most resistant to dissolution. It was defined constants of oligoperoxides transformation on modified samples of amorphous alloys and found that the highest electrocatalytic activity in the processes of dissociation multifunctional oligomers peroxide groups has nanostructured alloy Fe78,5Ni1,0Mo0,5Si6,0B14,0.
