Abstract： Semi-solidified flexible polishing discs are prepared for polishing tungsten carbide alloys by using SiO2 ，diamond，and SiO 2 /diamond mixed abrasives，and deionized water is used as the polishing solution to avoid contamination.Based on the mechanical properties of the flexible substrate of polishing discs，the polishing performance of tungsten carbide specimens with diffrent kinds of abrasives was investigated，and he surface quality after processing was analyzed.Results show that：after the use of a mixed abrasive disc polishing with wSiO2/wdiamond=2：3 ， the surface roughness of the sample is reduced to 0.007μm ， and that is a reduction of 96% ，the surface deep scratches and pits are effectively removed，and the PV value is 0.17μm Compared with the sample surface after the use of a single SiO2 and diamond abrasive disc polishing，PV values are reduced by 81% and 64% ，respectively.
