TiC-reinforced MAX-phase high-entropy ceramic-based composite material and preparation method thereof
The invention relates to a method for preparing a TiC-reinforced MAX-phase high-entropy ceramic material-based composite material with excellent comprehensive mechanical properties, and the TiC-reinforced MAX-phase high-entropy ceramic material-based composite material prepared by the method. The method comprises the following steps: 1) batching and mixing TiC powder and MAX phase powder, wherein the MAX phase powder is any more than three transition metal MAX phase carbide powder; 2) dispersing mixed powder obtained in step 1) in a grinding aid, performing ball milling to obtain ceramic slurry, performing vacuum drying, and sieving; 3) putting the mixed powder obtained in step 2) into a steel mold, and carrying out pre-pressing forming to obtain a ceramic blank; and 4) putting the ceramic blank obtained in step 3) into a graphite mold, and carrying out pressure sintering in a vacuum environment. A TiC second phase is introduced into the MAX-phase high-entropy ceramic matrix, so that the performance of the material is further improved.
本发明涉及一种制备具有优异综合力学性能的TiC增强MAX相高熵陶瓷材料基复合材料的方法，以及由该方法制备得到的TiC增强MAX相高熵陶瓷材料基复合材料。所述方法包括如下步骤：1)将TiC粉末与MAX相粉末，进行配料混合，所述MAX相粉末为任意三种以上的过渡金属MAX相碳化物粉末；2)将在步骤一得到的混合粉末分散于助磨剂中，进行球磨得到陶瓷浆料，并进行真空干燥，并进行过筛；3)将步骤二得到的混合粉末置于钢模中，进行预压成形，得到陶瓷素胚；4)将步骤三得到陶瓷素胚置于将石墨模具中，在真空环境下压力烧结。通过在MAX相高熵陶瓷基体中引入TiC第二相进一步提升材料的性能。
