We tested Fe73.1Cu1.0Nb3.0Si15.5B7.4 amorphous alloy for changes in the magnetic properties accompanying the transition from the strip form into a powder and after modification with polymeric coatings. It is shown that the dispersion down to particles smaller than 10 μm in size and the procedure of modification do not, in fact, worsen the magnetic properties of the alloy.
The phenomenon of alternation of active and passive periods of the redox processes on the surfaces of electrodes made of amorphous metal alloys based on Fe is established by the voltammetric method. The sequence of electrochemical reactions enable us to explain the time periodicity of the variations of currents and potentials of spontaneous dissolution of these alloys.
