Magnetic Abrasives Developed by Mechanical Alloying Method

Magnetically Assisted Abrasive Finishing (MAAF) processes are most suitable for obtaining quality finish on metallic as well as non-metallic surfaces. In these processes, the cutting forces are generated and these forces are controlled by magnetic field developed between the electromagnetic poles and magnetic abrasives. In spite of remarkable results of MAAF processes, the major constraint towards commercial adoption of this technology is the non-availability of cost-effective magnetic abrasives. The manufacturing techniques for preparing magnetic abrasives are time consuming and complicated therefore the existing magnetic abrasives are very costly. The aim of the present study is to develop and explore the usage of alternative magnetic abrasives, which are cost effective. In the present work, magnetic abrasives were prepared by mixing ferromagnetic powder, abrasive powder with Mechanical Alloying. To compare the performance of developed magnetic abrasives, two more types of magnetic abrasives were prepared by using sintering method and simple mixing method.
