Alumina-fiber-enhanced hydroxyapatite ceramic-based composite material and preparation method thereof
The invention discloses an alumina-fiber-enhanced hydroxyapatite ceramic-based composite material and a preparation method thereof. The material is characterized in that the material is prepared from the raw materials of, by weight, 70-80 parts of hydroxyapatite, 4-8 parts of acrylamide, 0.2-0.4 parts of N,N'-methylene bisacrylamide, 0.04-0.08 parts of ammonium persulfate, 2-3 parts of polyvinyl alcohol, 3-5 parts of aluminum alloy powder, 1-2 parts of sodium lignosulfonate, 10-15 parts of modified alumina fiber, 7-9 parts of niobium nitride, 20-30 parts of ethanol, and 40-60 parts of deionized water. According to the invention, the alumina fiber with an antioxidant treatment is added as an enhancement phase of ceramic, and has the characteristics of enhancing the toughness, mechanical performances, wear resistance, hardness and high-temperature resistance of ceramic. With the added aluminum alloy powder, a three-dimensional network structure can be formed with a blank under high temperature, such that ceramic toughness and fracture resistance can be enhanced. According to the invention, the application range of the hydroxyapatite ceramic-based composite material is expanded.
