Electrochemical behaviour of Fe40Ni38Mo4B18 amorphous alloys in aqueous solution at high pH. Influence of the structural relaxation

Effect of irreversible structural relaxation on the electrochemical behavior of Fe78−xSi13B9Cr(x=3,4,7) amorphous alloys

“…Few studies on structural relaxation in amorphous alloys prepared by the melt-spinning method have been reported including corrosion resistance effects [11][12][13][14][15][16][17]. It was reported [12] that melt-spun amorphous Ni-19P alloys in different amorphous states showed significantly different potentiodynamic polarization curves.…”

Effect of the oxidation in the surface magnetic properties of as-quenched and relaxed Finemet alloy

“…Different works have been devoted to study the corrosion behavior of amorphous and nanocrystalline materials and the possibility of increasing its corrosion resistance [5][6][7] whilst others have studied the influence of corrosion on the magnetic properties of these materials [8][9][10]. In these articles it has been shown that oxidation is a superficial process and then, the surface magnetic properties are the most affected by it.…”

Effect of the oxidation in the surface coercive force of nanocrystalline alloy

“…Sometimes these devices have to work in aggressive mediums that can produce the oxidation of the core and so, a deterioration of the proper work of the sensor. In the last years, some studies have investigated the corrosion behaviour of these materials and the possibility of increasing their corrosion resistance [3,4], whilst others have studied the influence of the corrosion on the magnetic properties of these materials [5,6]. Considering that in amorphous and nanocrystalline materials, oxidation is a process that mainly affects the surfaces, it is fundamental to know the variation of the surface of magnetic properties with oxidation in these materials in order to tailor them to be used in the above mentioned devices.…”
