Synthesis and Characterization of Sintered Magnetic Abrasives Used in Advance Finishing Processes Through Powder Metallurgy Route

Abstract

The magnetic field-assisted surface finishing process needs a sintered magnetic abrasive powder which could be a mixture of SiC and CIP particles. Tube furnaces have been used to develop SiC-based sintered magnetic abrasives. The focus of this article is to investigate the anticipated results and to carry out the fabrication setup of sintered magnetic abrasive for the super-finishing of composite materials and their coating. The article depicts a significant effect on the mechanical properties such as microhardness and compressive strength and analyzes SiC and CIP composite-based microstructure. The synthesis of the powder involves four major processes like blending; compaction and sintering. Characterization of sintered magnetic abrasives has been done using SEM, EDS, XRD to study morphology, chemical composition, crystallography, and magnetic properties. The results have been compared with the un-bonded magnetic abrasives. This paper also presents a brief literature review of the state-of-the-art technology of high-performance surface finishing processes used in manufacturing industries. Finally, the downside and stray aspects of the related literature are spotlighted and a list of prospective issues for future research directions is recommended.
