More Information
Summary:The invention discloses a preparation method of a zirconium boride/carbon fiber toughened titanium boride-based composite ceramic cutting tool material, which comprises the following steps: preparing zirconium boride, carbon fiber and titanium boride into slurry, uniformly mixing and drying to obtain composite ceramic powder, pre-pressing into a blank, and finally performing vacuum hot pressing sintering on the blank to obtain the titanium boride-based ceramic cutting tool material. The vacuum hot pressing sintering process comprises the steps that the vacuum degree in a furnace is lower than 0.01 MPa, the initial pressure before sintering is set to be 15 MPa, the pressure intensity is increased to 30 MPa in the heat preservation stage, pressure relief is conducted after heat preservation is completed, the temperature rise speed is 27.5 DEG C/min, the temperature reaches 1650 DEG C from the room temperature, heat preservation is conducted for 60 min, and then cooling is conducted along with the furnace.
