High-strength and high-toughness B4C composite bulletproof ceramic material and preparation method thereof
The invention relates to a high-strength and high-toughness B4C composite bulletproof ceramic material and a preparation method thereof. Comprising the following steps: firstly, selecting B4C, TiC and SiCw as raw materials, taking B4C as a main phase, taking TiB2 and C generated by chemical reaction of TiC and B4C as a second phase, and adding SiCw; mixing the powder according to a certain volume ratio, and sequentially carrying out wet ball milling and rotary evaporator drying on the mixed powder; and finally, sintering the powder in a discharge plasma sintering furnace, and preparing the B4C-TiB2-SiCw bulletproof composite material with the advantages of high compactness, high strength, high hardness, high toughness and the like by regulating and controlling the raw material ratio and the sintering process. The B4C-TiB2-SiCw bulletproof composite material prepared by the method is uniform in phase distribution, and nano-particles and layered C generated by reaction have better pinning and crack deflection effects.
本申请涉及一种高强高韧B4C复合防弹陶瓷材料及制备方法。包括首先选取B4C、TiC、和SiCw作为原料，以B4C为主相，TiC与B4C经化学反应生成的TiB2与C为第二相，并添加SiCw。然后按照一定体积比例混合粉体，将混合粉体依次经湿法球磨，旋转蒸发仪干燥。最后在放电等离子体烧结炉中对粉体进行烧结，通过调控原料配比以及烧结工艺，制备获得了具有高致密、高强度、高硬度、高韧性等优点的B4C‑TiB2‑SiCw防弹复合材料。采用该方法制备的B4C‑TiB2‑SiCw防弹复合材料各相分布均匀，反应生成的纳米颗粒和层状C具有更好的钉扎与裂纹偏转作用。
