Abstract

Abstract

Vitrified bond ultrafine diamond wheels with cellular structures were prepared by space placeholder method and solid particles sintering.The effect of sintering system on the cellular structures of the wheels was studied via the microstructure, the porosity and the bending strength of the wheels.The results show that the optimum sintering temperature of manufacturing ceramic bond ultrafine diamond wheels with cellular structures is 750℃,and the holding time is 90 min, thus the porosity and the bending strength of the prepared samples are 78% and 15 MPa.
