论文摘要
我们已经对七个不同组成磁弹性谐振平台的磁性,磁弹性和腐蚀性特性进行了研究。对于某些应用,例如结构性健康监测,这些材料不仅必须具有良好的磁力学特性,而且还必须具有高耐腐蚀性。在成分Fe(73-X)NixCR5SI10B12的制成金属玻璃中,Fe/Ni比变化(Fe + Ni = 73%,AT。),从而改变了磁性和磁弹性性能。为了达到所需的良好耐腐蚀性,添加了少量的铬(CR5)。如预期的那样,所有研究的特性随样品的组成而变化。含有比Fe含量高的合金在室温下不会显示磁性,而铁富合金不仅表现出良好的磁性特性,而且表现出良好的磁弹性弹性,其磁弹性耦合系数在x = 0的0.41中高达0.41,而在Fe73ni0cr5SI10B12中,仅含有Fe73ni0cr5SI10B12(不是Ni,而不是Ni)。关于耐腐蚀性,我们发现这些特性的连续降解随着Ni含量的增加而增加。因此,对于X = 0组成的46.74 mV,腐蚀电位从46.74 mV降低,Fe73ni0cr5SI10B12至-239.47 mV的X = 73组成FE0NI73CR5SI10B12。
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 Fe(73-x)NixCr5Si10B12, the Fe/Ni ratio was varied (Fe + Ni = 73% at.) thus changing the magnetic and magnetoelastic properties. A small amount of chromium (Cr5) 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 x=0 in the Fe73Ni0Cr5Si10B12 (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 x=0 composition, Fe73Ni0Cr5Si10B12 to -239.47 mV for the x=73 composition Fe0Ni73Cr5Si10B12.
