“…As a smart material, it can react quickly to the changes in magnetic¯eld within milliseconds. [1][2][3] Due to the attractive properties of MRF such as the continuous adjustability, the actively controllable nature and the low energy consumption, it has a wide range of applications in machinery manufacturing, auto parts, precision machining, aerospace, biomedical and other applications. [4][5][6] In contrast, certain problems in MRF still exist, which limit the corresponding application eld, mainly in the settlement stability becoming poor, the high cost and the shear stress is not sufciently high.…”

In order to analyze the e®ects of nano-diamond on the performance of magnetorheological°uids (MRFs), in this paper, the MRF-1 with a 2% mass fraction in nano-diamond and the MRF-2 without nano-diamond were prepared by the carbonyl iron powder as the dispersed phase and the synthetic mineral oil as the continuous phase. The viscosity and shear stress of MRFs under di®erent magnetic¯elds were measured by the Anton-Paar rheometer (MCR 302). The MRF settling stability was studied by a standing observation method. A four-ball wear machine was utilized for the wear test at 0.1 T of magnetic¯eld, whereas the magnetic¯eld was provided by an external coil. Also, the three-dimensional white light interferometer was utilized to observe the surface of the ball wear spot, in order to determine the MRF friction properties. The results demonstrated that the nano-diamond had a signi¯cant increase in the surface wear. The shear yield strength and settling stability of the MRF could be highly enhanced. The higher the strength of the magnetic¯eld was, the higher the di®erence in the shear yield strength was. These phenomena demonstrated that the physical properties of the nano-diamond could have a higher impact on MRF, which was of high signi¯cance to the preparation of MRFs with excellent performance.

Aiming to study the effect of particle size on the wear property of magnetorheological fluid (MRF), experiment materials, preparation process, and test methods are elaborated, and three different MRF samples consisting of particles of different size are prepared. Test experiments are carried out and the effect of particle size on the wear property of MRF is discussed. Moreover, the microstructures of particles extracted from MRF obtained before and after the wear experiments are observed by scanning electron microscope (SEM). Experimental results show that the particle size has a significant effect on wear property of MRF. Furthermore, the MRF with particles of 1.5–2.8 μm diameter on average is good for the requirement of engineering applications.
