137 アモルファス混合流体による磁気流体研磨に関する研究(S34-3 複雑流体の流れとその応用(3),S34 複雑流体の流れとその応用)  [in Japanese] 137 Study of magnetic fluid polishing utilizing amorphous compound fluid  [in Japanese]

As a new intelligent or smart fluid, we have proposed an amorphous compound fluid (ACF). This fluid has nm-sized magnetite and μm-sized amorphous particles in a solvent. In this report, we apply the ACF to a float polishing. And it shows the polishing results. It is clarified that the polishing effect is better utilizing ACF than MCF under a polishing condition of small clearance between the polishing and polished surfaces. The cause is due to the formation of string- and network-like clusters of ACF occurred by the remanent magnetization of the amorphous particles.
