Abstract
Due to stable performance and great hardness of nickel-based superalloy, single magnetic abrasive finishing (MAF) is difficult to polish the nickel-based superalloy workpiece, which makes the grinding efficiency decrease. The effective combination of electrolytic polishing process (EPP) and magnetic abrasive finishing process can improve processing efficiency by reducing the influence of material hardness. In order to verify the feasibility of this method, large numbers of experiments on the electrolytic-magnetic abrasive finishing (EMAF) of nickel-based superalloy GH4169 were carried out. Experimental results show that the EMAF can change the surface component content of workpiece to reduce the material hardness and make the surface roughness value reduce significantly and the surface morphology smoother; the processing efficiency is improved by 50 %.
