Surface Finishing Composition For AFM Process and AFM Process Using the Same

Non-Confidential description of the invention

The invention relates to a surface finishing composition for use in AFM (Abrasive Flow Machining) process and the AFM process using the surface finishing composition. Particularly, the invention relates to a surface finishing composition containing fly ash such as coal fly ash, bagasse fly ash or a mixture. It provides an abrasive composition for use in AFM process of metal surface finishing comprising, 68 wt.% of fly ash abrasive, 20 wt.% of a viscoelastic carrier, and12 wt.% of a processing oil. Object of the invention is to provide a sustainable and less costly finishing composition/media for AFM process with rheological property comparable to the traditional media, which also helps in attaining surface finish quality comparable to the traditional media.
