Summary: Thermally sprayed tungsten carbide coating is widely used for wear resistance applications. In this study, magnetorheological fluid based finishing (MRF) process with diamond powder abrasive particles is used to achieve a nanolevel surface finish on pre-polished tungsten carbide coating. The incorporation of a chemical etchant in MRF results in a higher finishing rate. However, the MRF technique's effectiveness is limited at higher wheel velocities. To overcome this, CIPdiamond and CIP-diamond-graphene composite abrasives are introduced, which show higher material removal rates and better stability at elevated wheel speeds. The MRF process with CIPdiamond-graphene abrasives achieves the lowest surface roughness (Sa) of 55 nm and highest MRR.
