磁流变弹性抛光复合材料是一种以磁流变弹性体为粘结剂的新型抛光材料，针对现有抛光技术存在的加工效率低、加工过程难以控制等问题，研制开发了磁流变弹性抛光复合材料。设计了一套热磁力耦合装置，利用磁场辅助模压成型技术制备了各向同性和各向异性硅橡胶基磁流变弹性抛光复合材料。利用X射线衍射仪、光学显微镜、电子万能试验机和划痕仪对磁流变弹性抛光复合材料的微观结构和性能进行了表征。结果表明，磁流变弹性抛光复合材料是由橡胶和微米/纳米粒子组成的聚合物基复合材料，在制备过程中施加的磁场使磁流变弹性抛光复合材料内部呈现由铁粒子形成的链状和柱状。磁流变弹性抛光复合材料的压缩弹性模量和抗划伤性随着周围磁场强度的增加而增加。上述现象的主要原因与外加磁场引起的磁流变弹性抛光复合材料微观结构的变化有关。最后，通过磁流变弹性抛光复合材料在抛光中的简单应用，证明了磁流变弹性抛光复合材料可以应用于机械加工，实现磁控抛光。
Magnetorheological elastic polishing composites, a new type of polishing material using magnetorheological elastomers as a binder, were developed to solve the problems of low processing efficiency and difficulty controlling the machining process in current polishing technology. A set of heat–magnet–force-coupled devices was designed and used to prepare isotropic and anisotropic silicon rubber–based magnetorheological elastic polishing composites by magnetic field–assisted compression molding technology. Then, the microstructure and properties of magnetorheological elastic polishing composites were characterized by X-ray diffraction, optical microscope, electronic universal testing machine, and microscratch tester. The results show that magnetorheological elastic polishing composite is a polymer-based composite composed of rubber and micro/nanoparticles, and the magnetic field applied during the preparation process causes the interior of the magnetorheological elastic polishing composites to appear as chains and columns formed by iron particles. The compressive elastic modulus and scratch resistance of magnetorheological elastic polishing composites increase with the increase in the surrounding magnetic field strength. The main reason for the above phenomena is related to the change in the microstructure of magnetorheological elastic polishing composites induced by an external magnetic field. Finally, a simple application of magnetorheological elastic polishing composites in polishing proves that magnetorheological elastic polishing composites can be applied to mechanical processing to achieve magnetically controlled polishing.
