“…Inspiration for typical MRF applications can be drawn from unique means of using MRFs. A silicon carbide (SiC) additive was used by Bedi and Singh [ 137 ] to introduce an MRF‐based honing process as a new approach to the surface finishing of ferromagnetic engine internal cylinder parts. After 120 min, the MRF decreased surface roughness by 50–60% due to the finishing force provided by the mobile SiC during the rotational and reciprocation movement of the tool.…”

Magnetorheological fluids (MRFs) are functional materials, prepared by dispersing magnetic particles in a nonmagnetic carrier fluid, that exhibit a change in mechanical properties (e.g., increase in viscosity and yield stress) when subjected to a magnetic field. Change in mechanical properties is demonstrated by a fast (i.e., fraction of milliseconds) and reversible transition from a liquid‐ to a solid‐like state. This transition, due to a structural reorganization of magnetic particles in the carrier fluid, makes MRFs a valuable material for damping, breaking systems, medical and prosthetics, and robotics. Since the discovery of MRFs in 1948, developing MRF preparation methods that result in improved performance and the storage without oxidation and settling is paramount. This article presents a review on recent developments in the preparation process of MRFs with a special emphasis on the state of the art in additives and coatings used in enhancing MRF chemical, colloidal, and thermal stability. Recent advances in MRF materials and formulations that have increased yield stress and magnetic properties are discussed. Finally, this review analyses the present‐day challenges in MRF research and makes suggestions for the field to improve MRF stability and performance drawing on previous MRF work and work outside of the fields.

“…11 Also, these often cause various types of surface defects because of the direct interaction of the tool with the finishing surface and the action of uncontrollable finishing forces. 12 Therefore, to get a more qualitative finished surface of the cylindrical workpiece's inside surface, advanced finishing processes have been developed. The abrasive flow machining (AFM) 13,14 and rotational abrasive flow finishing (R-AFF) 15 are found capable to finish the interior surface of the cylindric and complex internal geometric shape of the workpieces.…”

A cylindrical barrel is a crucial part of the hydraulic cylinder that enables the mechanical system to apply high power to get the desired work, such as moving, pressing, and lifting the high-weight materials, done. The smoothness in the functioning of the machinery performing the tasks of these kinds is directly linked with the quality of the interior surface finish of the hydraulic cylinder’s cylindrical barrel. In this study, the inside surface of a real-time hydraulic cylinder's barrel is completed to achieve a fine finish. The cylindrical barrel of the hydraulic cylinder with a fine-finished internal surface causes the related machinery to consume less power to get the desired work done. The smooth functioning of different kinds of machinery is affected by the level of internal surface finish of the cylindrical barrel of the hydraulic cylinder. For investigating the best parameters of the magnetorheological finishing process over the interior surface of the hydraulic cylinder’s cylindrical barrel, the response surface methodology has been used. Through 60 min of magnetorheological-finishing using optimal finishing conditions, the final surface roughness is achieved up to 40 nm from 380 nm of initially honed roughness. Also, the improvement in dimensional and geometric accuracies has been analysed through surface waviness and circularity measurement before and after the magnetorheological-finished surface. Through the scanning electron microscopy tests, the enhancement in surface consistency of the cylindrical barrel of the hydraulic cylinder’s finished surface is analysed. The overall results demonstrate the significant importance of the rotating-magnetorheological honing process to fine finish the inside surface of the cylindrical barrel of the hydraulic cylinder.

The need for ultraprecision finishing has grown, and magnetic field-assisted finishing has shown potential for overcoming some challenges. This study evaluates the scientific production and identifies future directions of magnetic field-assisted finishing based on a bibliometric analysis. Using Bibliometrix, network mapping and descriptive analysis were performed on 1558 documents related to magnetic field-assisted finishing-related research published over the past 51 years. The results of the comprehensive literature reviewed showed that the theme exhibits a rising trend of 56% in the last 10 years, being mainly conducted by Chinese, Indian, and American researchers. Different geometries and materials can be finished and which had surface roughness ranges from sub-nanometer- to micrometer-scale. Surface finishing of freeform dies and molds, optical components, and medical devices have been standing out as current process applications in tooling, aerospace, and biomedical industries. AISI 304 stainless steel was the most tested metal. Finally, potential areas of research were identified in the coming years, which could lead to new fields of application for magnetic field-assisted finishing in industry.
