3O4@SiO2復(fù)合粒子，并將其應(yīng)用于鈦合金板材的磁流變拋光中。結(jié)果表明，與傳統(tǒng)磨粒相比，核殼結(jié)構(gòu)磨粒加工后可獲得更高的表面質(zhì)量。經(jīng)過20 min拋光后，工件面粗糙度達(dá)到了23 nm，并且有效地減少了劃痕。最后，對(duì)核殼結(jié)構(gòu)納米粒子的制備和應(yīng)用進(jìn)行了總結(jié)和展望，為核殼結(jié)構(gòu)納米粒子進(jìn)一步研究提供參考。;Preparation method of magnetic nanoparticles with core-shell structure was introduced, especially focusing on the preparation principle of sol-gel method, microemulsion method, and self-assembly technique. The application of core-shell nanoparticles in precision machining was discussed. The Fe3O4@SiO2 composite particles were prepared by sol-gel method and were applied to the magnetorheological polishing of titanium alloy plates. Results show that core-shell nanoparticles with higher surface quality can be obtained after processing, compared with those after conventional abrasives. After polishing for 20 min, the surface roughness of the workpiece reaches 23 nm and the scratches are effectively reduced. Finally, the preparation and application of core-shell nanoparticles are summarized and prospected to provide a reference for further research on core-shell nanoparticles."/>
