摘　　要：介绍一种新的磁性复合抛光体(M PT)的配制及检测方法.新的磁性抛光体是将磁性复合流体和磨粒、植物纤维素均匀混合,通过外加磁场压缩制成的,在磁场作用下为半固态.M PT的主要成分及规格:煤油基纳米直径F e3O4的磁流体(M F)、微米级直径的铁粉、微米级直径的纯A l2O3磨粒.对几种混合比例的M PT分别进行了SEM的显微观察和抛光作用力的三维检测,在给定压力下对M PT的剪切力和抛光性能进行了试验.结果表明:磁性复合抛光体的配比影响着M PT最大剪切力,具有承受剪切力大的磁性抛光体的抛光效果较好.该研究为复杂曲面的高效、高质量抛光提供了应用依据.A novel MPT（magnetic compound fluid polishing tool）has been developed and tested which is compounded of a MCF （magnetic compound fluid）, near solid state, involved in abrasive particles and plant fibre. The MPT consists of Fe3O4 magnetic fluid in nano size, Fe powder in micrometer size, and Al2O3 particles in micrometer size as well. The micro-conditions and mechanical characteristics of MPT were examined by means of SEM and 3D force meter respectively. The experimental results show that the rational rate of MPT affects its shearing force, that is： the higher the shearing force is, the better the polishing effects are. The research provides a fundament for complexity-surface polishing in both higher efficiency and quality.
