The Experiment Research on the Fluid Magnetic Abrasives

Abstract

The fluid magnetic abrasive (FMA) is a new type of intelligent material. The fluid magnetic abrasive (FMA) has typical liquid characteristics, when there is no external magnetic field around it. But when a strong magnetic field is applied, the viscosity of it will increase more than 100 times within a few milliseconds, and it will show the characteristics those are resemble to solid's. We call this feature as rheological property, of which because the workpiece can be finished by fluid magnetic abrasive (FMA). On base of researching on the micro-structure of fluid magnetic abrasive (FMA), the experiments and results are presented in this paper.
