Preparation method of ZTA ceramic reinforced iron-based composite material
The invention discloses a preparation method of a ZTA ceramic reinforced iron-based composite material, and belongs to the field of metal-based composite materials. A ZTA precursor generated through coprecipitation of solutions of aluminum ammonium sulfate, zirconium oxychloride, rare earth nitrate and the like and an iron precursor generated through coprecipitation of solutions of ferric chloride hydrate, ammonia water, hydrochloric acid and the like are fully stirred and mixed for liquid-liquid doping, and then the ZTA ceramic reinforced iron-based composite material is obtained through the processes of calcination, reduction, sintering and the like. A coprecipitation method is adopted, a high-temperature and high-pressure reaction kettle necessary for hydro-thermal synthesis is not needed, preparation of the ZTA ceramic reinforced iron-based composite material can be achieved at the room temperature and the normal pressure, the experimental conditions are reduced, and the experimental environment is improved. The ZTA ceramic precursor prepared by the method contains rare earth oxides with high chemical activity, and the rare earth oxides are enriched at the interface of the ceramic and an iron matrix when the composite material is sintered, so that the wetting angle of the ceramic and iron is reduced, and the compatibility between the ceramic and the iron is further improved.
本发明公开一种ZTA陶瓷增强铁基复合材料的制备方法，属于金属基复合材料领域。将硫酸铝铵、氧氯化锆、稀土硝酸盐等溶液共沉淀生成的ZTA前驱体与氯化铁水合物、氨水、盐酸等溶液共沉淀生成的铁前驱体充分搅拌混合进行液液掺杂，再经煅烧、还原、烧结等工艺得到ZTA陶瓷增强铁基复合材料。本发明采用共沉淀的方法，无需水热合成时所必须的高温高压反应釜，在室温常压下即可实现ZTA陶瓷增强铁基复合材料的制备，降低了实验条件并改善了实验环境。本发明制备的ZTA陶瓷前驱体中含有化学活性高的稀土氧化物，这些稀土氧化物在复合材料烧结时富集在陶瓷和铁基体的界面处，降低了陶瓷与铁的润湿角，进一步提高了陶瓷与铁之间的相容性。
