| Abstract Scope |
Magnetorheological fluids are a class of smart materials fabricated with magnetic particles (Fe, magnetite) embedded in a liquid carrier. Thus, the resulting composite mechanical behavior (viscosity, yield stress) can be fully controlled by an external magnetic field that alters the internal structure or disposition of those magnetic fillers. In this work we present results concerning the fabrication of such smart fluids by using high magnetization FeCo alloy nanoparticles and silicon oil as liquid matrix. This FeCo alloy is a soft ferromagnetic material with cubic structure and the highest known magnetization (about 230 emu/g). The final fabricated smart fluid has shown a yield stress as high as 2,73 kPa at 0,775 T applied field.
The possibility to use these fluidic composites that use these high magnetization FeCo alloy small nanoparticles in additive manufacturing processing of multifunctional materials will be also assessed. |
