将纳米铁基非晶合金粒子，经包覆后加入Ga-In-Ag合金液体中，制成的新合金载液磁性液体，除具有普通使用的以水、油、有机物等作为载液的磁性液体的主要用途外，还具有使用温度范围宽,导热和导电系数高等优点。但由于纳米非晶粒子与合金载液的相互作用使这类磁性液体稳定性差，限制了该材料的发展。利用本研究室在液体结构和性质研究方面的基础条件，研究金属非晶纳米粒子与Ga-In-Ag 合金载液之间的界面稳定性，主要包括纳米颗粒的涂覆过程研究，涂覆层对磁粘滞性及流动特性的影响，以及非晶颗粒表面涂覆层对磁性粒子团聚性及分散性的影响。探索适合于金属载液的新的非晶纳米颗粒的制作方法，建立非晶颗粒涂覆层成分与饱和磁化强度的关系，为研制和开发具有更宽工业应用价值的新合金载液磁性液体打下理论基础。

Magnetic fluids with alloy carrier liquids, fabricated by doping Fe-based amorphous particles into Ga-In-Ag alloy liquids, exhibit wide operating temperature range, high conductivity as well as high thermal conductivity compared with magnetic fluids used water, oil or other organic as carrier liquids. However, the poor stability resulted by the interaction between amorphous nanoparticles and alloy carrier liquid, limits the development of these magnetic fluids. Based on the research of liquid structure and properties in our laboratory, we will study the interface stability between metallic glass particles and Ga-In-Ag alloy carrier liquid. We will focus on the coating process of nanoparticles, and the effect of surface coating on the magneoviscous effect and flow properties. It is hoped to find the effect of surface coating on the aggregation and dispersity of nanoparticles. We will explore preparation methods of new amorphous nanoparticles, and establish the relation between the compositions of surface coating on the nanoparticles and saturation magnetization. The results will provide theoretical basis for research and development of new alloy carrier liquid based on magnetic liquid which has more wide industrial application values.
