Al2O3-ZrO2 multiphase ceramic particle as well as preparation method and application thereof
The invention discloses an Al2O3-ZrO2 multiphase ceramic particle as well as a preparation method and application thereof, and relates to the technical field of ceramic composite material preparation, the Al2O3-ZrO2 multiphase ceramic particle comprises an Al2O3/ZrO2 ceramic particle and a plurality of macroscopic pits formed on the surface of the Al2O3/ZrO2 ceramic particle, the maximum scale of projection of the pits is 0.3 mm, and the maximum height difference between the pits and the surface is 0.3 mm. The surfaces of the Al2O3-ZrO2 multiphase ceramic particles provided by the invention have certain roughness, the shape and the structure are controllable, the surfaces are free of cracks, the wear resistance of a composite material can be improved in the subsequent application of the Al2O3-ZrO2 multiphase ceramic particles as a reinforcing material of a steel material, meanwhile, the composite material can be prepared at low cost, and the wear resistance of the composite material is improved by times.
本发明公开了一种Al2O3‑ZrO2复相陶瓷颗粒及其制备方法和应用，涉及陶瓷复合材料制备技术领域，该Al2O3‑ZrO2复相陶瓷颗粒包括Al2O3/ZrO2陶瓷颗粒以及成型于Al2O3/ZrO2陶瓷颗粒表面的多个宏观凹坑，凹坑的投影最大尺度为0.3mm，凹坑距离表面最大高差0.3mm。本申请提供的Al2O3‑ZrO2复相陶瓷颗粒表面具有一定的粗糙度，并且其形状和组织可控，表面无裂纹，有利于在后续作为钢铁材料的增强材料的应用中，提升复合材料的耐磨性，同时还可以实现低成本制备复合材料，实现成倍提高复合材料耐磨性。
