摘要

采用X射线衍射（XRD）、扫描电子显微镜（SEM）、电化学工作站、振动样品磁强计（VSM）研究Mo元素掺杂对LaFe_11.5Si_1.5磁制冷材料相组成、耐腐蚀性能和磁性能的影响。结果表明：随着Mo元素的加入，α-Fe相及富La相不断增多。Mo原子分布在NaZn₁₃型结构的相（简称1：13相）及α-Fe相中，并未出现在富La相中。对耐腐蚀性能的研究表明，当Mo含量从x=0提高至x=0.2，LaFe_11.5-xMo_xSi_1.5合金的腐蚀电位升高，腐蚀电流密度降低，说明热力学稳定性以及耐腐蚀性均提高。但是当Mo含量增加到x=0.3时，耐腐蚀性能下降。对磁性能的研究表明，LaFe_11.5-xMo_xSi_1.5在0~3 T磁场变化下的最大磁熵变分别为18.51 J/（kg·K）（x=0），16.24 J/（kg·K）（x=0.1）和5.68 J/（kg·K）（x=0.2）。

Abstract：

The effect of Mo on phase formation, corrosion resistance and magnetic property of LaFe_11.5Si_1.5 magnetic refrigeration materials were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), electrochemical workstation and vibrating sample magnetometer (VSM). The results show that the amount of α-Fe phase and La-rich phase increases with the increase of Mo content. Mo is distributed in both NaZn₁₃-type structure phase (1:13 phase for short) and α-Fe phase, but it does not appear in the La-rich phase. The studies on the corrosion resistance show that the corrosion potential increases and corrosion current density decreases with the increase of Mo content from x=0 to x=0.2, which indicate that the thermodynamic stability and corrosion resistance are improved. However, the corrosion resistance decreases while x increases to 0.3. The maximum magnetic entropy changes of LaFe_11.5-xMo_xSi_1.5 under a magnetic field change of 0-3 T are about 18.51 J/(kg·K)(x=0), 16.24 J/(kg·K)(x=0.1) and 5.68 J/(kg·K)(x=0.2), respectively.

Key words： magnetic refrigeration material La(Fe, Si)₁₃ corrosion resistance magnetic property
