采用自蔓延高温合成和使用HfC陶瓷粉末的准热等静压技术制备了致密ZrC陶瓷材料及复合陶瓷涂层。使用XRD、SEM等仪器对涂层的物相与组织形貌进行了分析。结果表明:复合涂层主要由大块的HfC颗粒和细小的ZrC晶粒组成。它是由HfC粉末空隙的ZrC晶粒与HfC粉末冶金结合形成的。涂层整体致密,孔隙率低;热震试验显示涂层具有良好的结合力。 The dense ZrC ceramic materials and composite ceramic coatings were prepared by the self-propagating high temperature synthesis and quasi-hot isostatic pressing using HfC ceramic powders. The phase and microstructure of the coating were analyzed by XRD, SEM and other instruments. The results show that the composite coatings consist of large HfC particles and fine ZrC grains. It is formed by HfC powder gap ZrC grains and HfC powder metallurgy. The whole coating is dense and the porosity is low. The thermal shock test shows that the coating has a good binding force.
