The invention provides a wear-resistant ceramic-based material, and relates to the technical field of wear-resistant ceramic materials. The wear-resistant ceramic-based material comprises the following components in parts by mass: aluminum oxide powder, silicon dioxide powder, nickel powder, zirconium oxide powder, tungsten carbide powder, chromium carbide and quartz sand powder. By re-pressing the sintered ceramic rough blank, the internal density of the ceramic-based material is larger, the overall tensile strength of the ceramic-based material is improved, and by adding tungsten carbide and chromium carbide, the wear resistance, oxidation resistance and explosion resistance of the ceramic-based material can be effectively improved. Through the heat treatment process for annealing the ceramic-based material, the residual stress can be effectively eliminated, the size is stabilized, the deformation and crack tendency is reduced, grains are refined, the structure is adjusted, the structure defect is eliminated, the hardness can be reduced, and the impact toughness of the ceramic-based material can be improved.
本发明提供一种耐磨陶瓷基材料，涉及耐磨陶瓷材料技术领域。该耐磨陶瓷基材料，按质量份数包括以下成分：三氧化二铝粉、二氧化硅粉、镍粉、氧化锆粉、碳化钨粉、碳化铬和石英砂粉。通过对烧结后的陶瓷粗坯进行复压，使得陶瓷基材料的内部密度更大，有利于提高陶瓷基材料整体的抗拉强度，通过添加碳化钨和碳化铬，可以有效地提高陶瓷基材料的耐磨性能和抗氧化性能以及提高抗爆能力，通过对陶瓷基材料进行退火的热处理工艺，可以有效地提高消除残余应力，稳定尺寸，减少变形与裂纹倾向，细化晶粒，调整组织，消除组织缺陷，且能够达到降低硬度提高陶瓷基材料的冲击韧性。
