“…However, ball milling powder with higher hardness will introduce impurity elements Fe and Cr, so the hardness of the material is not easy to be too high, while taking into account easy access to air, the material is not easy to oxidize, currently suitable for the preparation of high-quality powder with Cu-based targets. 3 h, (c) 6 h, (d) 12 h, (e) 24 h [4] . Taking the planetary grinding method as an example, the production process is as follows [5] : before grinding, the grinding tank is cleaned and dried, and then loaded into the grinding pieces, grinding additives, protective liquid and other materials, the gas in the grinding tank is extracted and filled with argon, and the sound insulation shield is closed after installation to the specified position of the instrument, and the grinding is carried out according to demand.…”

“…The first group of methods includes the so-called top-down approaches, which involves reducing the size of bulk materials to nanoscale through the use of mechanical processes and lithography. Among them can be distinguished mechanical alloying [ 79 ], high-energy ball milling [ 80 ], equal-channel angle pressing [ 81 ], high-pressure torsion [ 82 , 83 ], accumulative roll bonding [ 84 ], chemical etching [ 85 ], laser ablation [ 86 ], and various lithography techniques [ 87 , 88 , 89 ]. Top-down methods of synthesis of nanostructured materials allow us to produce ideal periodic structures without any defects and in a repeatable manner, but often require advanced and expensive equipment, e.g., ion beam, E-beam, X-ray, and interference lithographic techniques.…”

In the last few decades, the development and use of thin films and nanostructured materials to enhance physical and chemical properties of materials has been common practice in the field of materials science and engineering. The progress which has recently been made in tailoring the unique properties of thin films and nanostructured materials, such as a high surface area to volume ratio, surface charge, structure, anisotropic nature, and tunable functionalities, allow expanding the range of their possible applications from mechanical, structural, and protective coatings to electronics, energy storage systems, sensing, optoelectronics, catalysis, and biomedicine. Recent advances have also focused on the importance of electrochemistry in the fabrication and characterization of functional thin films and nanostructured materials, as well as various systems and devices based on these materials. Both cathodic and anodic processes are being extensively developed in order to elaborate new procedures and possibilities for the synthesis and characterization of thin films and nanostructured materials.

“…So far, Vadillo and Gutiérrez et al fabricated Fe-Co nanoparticles with high saturation magnetization by using the chemical reduction technique, the results showed that the Fe-Co nanoparticles based MRFs have excellent MR properties, but it should be noted that the fabricated Fe-Co nanoparticles also have high coercivity and remanent magnetization [23,24]. Saraswathi et al fabricated Fe-Co nanoparticles by utilizing a planetary high-energy ball mill, the fabricated Fe-Co nanoparticles have higher saturation magnetization and high coercivity [25]. Although Fe-Co nanoparticles with high saturation magnetization were successfully synthesized in these works, the reversibility and repeatability of the prepared MRFs was reduced due to the high coercivity and remanent magnetization of the particles.…”

Fe-Co alloys exhibit an excellent saturation magnetization, which makes them become a potential candidate for the high property magnetic particles in magnetorheological fluids (MRFs). How to decrease their coercivity and residual magnetization without sacrificing the saturation magnetization is a crucial problem to be solved. In this study, Fe-Co nanoparticles were prepared by DC arc discharge and further disposed through low temperature annealing in Ar atmosphere. The successful synthesis of Fe-Co nanoparticles was proved by XRD and EDS. The VSM results revealed that the prepared Fe-Co nanoparticles had a saturation magnetization of 208 emu/g, while the coercivity and remanent magnetization were 58 Oe and 5.8 emu/g, respectively. The MR properties of Fe-Co nanoparticles based MRFs (FeCoNP-MRFs) with 10% particles by volume fraction were systematically investigated. The FeCoNP-MRFs showed up to 4.61 kPa dynamic shear stress at 436 kA/m magnetic field and an excellent reversibility. The MR properties of FeCoNP-MRFs were fitted well by Bingham and power law model, and described by Seo-Seo and Casson fluid model. Meanwhile, the sedimentation ratio of FeCoNP-MRFs was still 87.3% after 72 hours, indicating an excellent sedimentation stability.
