Alumina-fiber-enhanced boron carbide ceramic-based composite material and preparation method thereof
The invention discloses an alumina-fiber-enhanced boron carbide 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, 15-25 parts of vanadium nitride, 60-80 parts of boron carbide, 10-13 parts of modified alumina fiber, 3-5 parts of chromite powder, 0.02-0.03 part of t-butyl peroxybenzoate, 5-7 parts of isoprene, 2-3 parts of sodium alginate, 0.2-0.4 part of N-methylol acrylamide, 25-30 parts of ethanol, and 40-50 parts of deionized water. According to the invention, the alumina fiber processed through an antioxidant treatment is adopted as an enhancement phase of ceramic, such that ceramic toughness, mechanical performances, wear resistance, hardness and high-temperature resistance can be enhanced. The added chromite powder has the characteristics of melting resistance, high-temperature resistance, high-temperature friction coefficient enhancing property, and heat recession ameliorating property. Therefore, ceramic wear resistance and high-temperature resistance can be enhanced.
