The invention provides a high-performance composite ceramic particle reinforced iron-based composite material. Composite ceramic particles are made of rare-earth modified aluminium oxide/zirconium carbide; and the modified aluminium oxide/zirconium carbide is Ce modified aluminium oxide/zirconium carbide. The Ce modified aluminium oxide/zirconium carbide is prepared by adopting the following method comprising the following steps of (1) preparing a permeation liquid: weighing rare earth CeC13 and NH4C1, sufficiently dissolving rare earth CeC13 and NH4C1 with a small amount of methanol, and preparing a rare earth Ce containing methanol permeation liquid; and (2) performing diffusing permeation: adding aluminium oxide/zirconium carbide in a diffusing permeation furnace, dropwise adding the rare earth Ce containing permeation liquid in the diffusing permeation furnace, controlling the dropwise adding speed, and taking out a sample after the diffusing permeation furnace is freely cooled tothe room temperature. The interface wettability of additional particles and an iron matrix is improved, the sintering defects are reduced, and the interface bonding is enhanced.
本发明提供了一种高性能复合陶瓷颗粒增强铁基复合材料，所述复合陶瓷颗粒为稀土改性氧化铝/碳化锆，改性氧化铝/碳化锆为Ce改性氧化铝/碳化锆。Ce改性氧化铝/碳化锆由以下方法制备而成：（1）渗液的配置：称取稀土CeCl、NHCl，用少量甲醇将其充分溶解后，配置成浓度为5.0%的含稀土Ce的甲醇渗液；（2）扩渗：将氧化铝/碳化锆加入至扩渗炉中，向扩渗炉中滴加含稀土Ce的渗液，控制滴加速度，待扩渗炉自由冷却到室温后，取出样品。本发明改善外加颗粒与铁基体界面润湿性，减少烧结缺陷，从而加强界面结合。
