Abstract

The invention discloses an alumina ceramic matrix composite for cutters, and a preparation method of the alumina ceramic matrix composite. The alumina ceramic matrix composite is prepared from the following main components: zirconium diboride, silicon carbide and titanium powder, and is prepared by adding carbon fibers, boron nitride, ammonium persulfate, a chitosan acetic acid solution, paraffin emulsion, hydroxypropyl acrylate, heavy calcium carbonate, sodium alginate, hesperiden, 7-aminoquinoline, a coupling agent, a sintering aids and deionized water, and carrying out the technologies such as ball milling, mixing, ultrasonic sound, molding, degumming, spraying, mould pressing, vacuum impregnation and hot pressed sintering. The alumina ceramic matrix composite has higher toughness, is excellent in wear resistance, bending resistance and hardness index, and can meet the requirements of the industry, thus having better application prospect.
