Chemomechanical magnetorheological finishing: Process mechanism, research trends, challenges and opportunities in surface finishing

Abstract

Chemomechanical magnetorheological finishing (CMMRF) has emerged as a nanofinishing method that combines the characteristics of chemical mechanical polishing (CMP) and magneto-rheological finishing (MRF). The CMMRF process was designed to take into account both the chemical and mechanical effects that occur during the finishing process. In the field of material processing science, this article delves into the fundamentals of the CMMRF method. The potential research patterns linked to CMMRF are assessed and their benefits are determined. Furthermore, the challenges of improving CMMRF process capabilities, as well as the wide futuristic opportunities of the research sector, are emphasised, along with meeting all industrial needs. The findings of this analysis paper will also aid researchers in the field of advanced finishing in identifying process realisation for better results.

Development and experimental investigation of magnetic abrasive finishing of 17-4PH steel

“…Magnetic field-assisted finishing is a versatile method that can be used for finishing, deburring and cleaning a wide range of end products. This approach includes techniques such as magnetic float polishing, magneto-rheological finishing, 10 alternating-magnetic field-assisted finishing, 11 magnetorheological shear thickening polishing, 12 and magnetic abrasive finishing (MAF). In MAF, Magnetic Abrasive Particles (MAPs) form a flexible magnetic abrasive brush (FMAB) in the presence of magnetic field.…”

Atomistic study on the effect of the size of diamond abrasive particle during polishing of stainless steel

“…This has happened due to the chemical interaction of abrasive particles with workpiece to implement chemically assisted material removal from the surface of SS304L material, thus the surface and sub-surface damages have been mitigated. Where CMMRF process combines the characteristics of chemical mechanical polishing (CMP) and magneto-rheological finishing (MRF) processes [10] to utilise beneficial attributes of both chemical and mechanical effects during the material removal using flexible magnetic tool of MRF technique. MRF based finishing utilises Magnetorheological fluid (MR) under influence of magnetic field to control the finishing forces to control the material removal at nanometric scale.…”

Effect of sintering routes on CIP/EIP – Al2O3 composite magnetic abrasive for chemo-mechanical magneto-rheological finishing of aluminium 6061

“…chemomechanical magnetorheological finishing (CMMRF), which is a combination of CMP and MRF. 32 There is a need for research to develop advanced magnetic abrasives for the CMMRF process and study the challenges it faces, such as declining magnetic and rheological properties, enhanced microstructure, good thermal stability and high MRR, and nano-scale level finishing with zero-defect. As an outcome, we reduce finishing challenges to meet industrial demand for superior finish metallic surfaces.…”
