Preparation method of bionic structure boron carbide ceramic-metal composite material
The invention provides a preparation method of a bionic structure boron carbide ceramic-metal composite material. The preparation method comprises the following steps: 1) preparing an adhesive aqueoussolution; 2) uniformly wetting the spliced side surface of a boron carbide ceramic billet by using the adhesive aqueous solution, and uniformly coating the spliced side surface with metal powder; 3)measuring the thickness of the coated metal powder layer, performing a step 4) if a preset coating thickness is reached, and if the preset coating thickness is not reached, skipping to the step 2); 4)tightly arranging the boron carbide ceramic billet in a hot-pressing sintering mold in a spliced side surface attaching manner; 5) putting the hot-pressing sintering mold into a hot-pressing sintering furnace, and sintering under a vacuum condition; and (6) after sintering is completed, naturally cooling, taking out the sample, and demolding to obtain the bionic structure boron carbide ceramic-metal composite material. According to the invention, the integral molding is performed by using the interface diffusion reaction between the ceramic billet and the metal powder at a high temperature.
本发明提供一种仿生结构碳化硼陶瓷‑金属复合材料的制备方法，包括如下步骤：步骤1)：配置粘接剂水溶液；步骤2)：先用所述粘接剂水溶液均匀润湿碳化硼陶瓷坯体的拼接侧面，再在所述拼接侧面均匀涂敷金属粉末；步骤3)：测量涂敷的金属粉末层厚度，若达到预定涂敷厚度则进行步骤4)；若未达到预定涂敷厚度则跳转至步骤2)；步骤4)：将所述碳化硼陶瓷坯体按照拼接侧面相贴合的方式紧密排放在热压烧结模具中；步骤5)：将热压烧结模具放入热压烧结炉内，在真空条件下进行烧结；步骤6)：烧结完成后，自然冷却，取出样品，脱模得到仿生结构碳化硼陶瓷‑金属复合材料。本发明利用高温下陶瓷坯体和金属粉末间的界面扩散反应而一体成型。
