“…With P addition in the Fe 45 C 16 Mo 16 C 15 B 10 glassy alloy, the kinetics of passivation and composition of passive film are improved in HCl solution. While with Si replacement of P, the corrosion resistance can be enhanced due to the formation of passive film composed of chromium oxide with some amounts of silica [67].…”

Metallic Glasses - Formation and Properties

View full text Add to dashboard Cite

Metallic glasses exhibit excellent corrosion resistance and electrocatalytic properties, and present extensive potential applications as anticorrosion, antiwearing, and catalysis materials in many industries. The effects of minor alloying element, microstructure, and service environment on the corrosion resistance, pitting corrosion, and electrocatalytic efficiency of metallic glasses are reviewed. Some scarcities in corrosion behaviors, pitting mechanism, and eletrocatalytic reactive activity for hydrogen are discussed. It is hoped that the overview is beneficial for some researcher paying attention to metallic glasses.

“…Nevertheless, not only Ni, but also the presence of other elements in their composition will determine the corrosion resistance of the samples [12][13][14]. It has been already reported by several authors that the addition of certain elements, such as Cr [15,16] or Mo [17] substantially increases the corrosion resistance of the metallic alloys. In fact, in one of our previous works we observed how the addition of Cr improves the corrosion resistance of these type of magnetoelastic alloys [18].…”

We have performed a study of the magnetic, magnetoelastic, and corrosion resistance properties of seven different composition magnetoelastic-resonant platforms. For some applications, such as structural health monitoring, these materials must have not only good magnetomechanical properties, but also a high corrosion resistance. In the fabricated metallic glasses of composition 73− 5 10 12 , the Fe/Ni ratio was varied (Fe + Ni = 73% at. ) thus changing the magnetic and magnetoelastic properties. A small amount of chromium (Cr 5 ) was added in order to achieve the desired good corrosion resistance. As expected, all the studied properties change with the composition of the samples. Alloys containing a higher amount of Ni than Fe do not show magnetic behavior at room temperature, while iron-rich alloys have demonstrated not only good magnetic properties, but also good magnetoelastic ones, with magnetoelastic coupling coefficient as high as 0.41 for = 0 in the 73 0 5 10 12 (the sample containing only Fe but not Ni ). Concerning corrosion resistance, we have found a continuous degradation of these properties as the Ni content increases in the composition. Thus, the corrosion potential decreases monotonously from 46.74 mV for the = 0, composition 73 0 5 10 12 to −239.47 mV for the = 73, composition 0 73 5 10 12 .

“…Many researches about corrosion properties of Fe-bases metallic glasses have been done in last decades. The corrosion resistance can be improved by an addition of Si element in the Fe-CrNi alloy [1]. The Fe-Cr-Mo-C-B amorphous alloy [2] exhibits a low corrosion rate of 10 À3 w10 À2 mm/y as the formation of chromiumrich passive films in hydrochloric solution.…”
