The invention discloses a novel ceramic bearing composite material, and relates to the technical field of ceramic materials. The novel ceramic bearing composite material is prepared from the followingraw materials in parts by weight: 45-65 parts of silicon nitride, 10-20 parts of carbon graphite powder, 10-15 parts of zirconium oxide, 5-10 parts of aluminum oxide, 3-5 parts of cerium oxide, 3-5 parts of yttrium oxide, 3-5 parts of titanium powder, 0.8-1.2 parts of a binder and 0.2-0.5 part of a defoaming agent. In addition, the invention also provides a preparation method of the novel ceramicbearing composite material. The novel ceramic bearing composite material has excellent wear resistance, high strength and high toughness, so that a bearing works under a high-temperature condition, is not easy to deform, wear and break, the service lifetime of the bearing is prolonged, the sintering temperature is relatively low, the preparation process is simple, and the processing cost is relatively low.
本发明公开一种新型陶瓷轴承复合材料，涉及陶瓷材料技术领域。本发明公开的新型陶瓷轴承复合材料是由以下重量份数的原料组成：氮化硅45‑65份、碳石墨粉10‑20份、氧化锆10‑15份、氧化铝5‑10份、氧化铈3‑5份、氧化钇3‑5份、钛粉3‑5份、粘结剂0.8‑1.2份和除泡剂0.2‑0.5份。此外，本发明还提供了新型陶瓷轴承复合材料的制备方法。本发明的新型陶瓷轴承复合材料具有优良的耐磨性能、高强度和高韧性，使轴承在高温条件下工作，不易变形，不易磨损，不易断裂，延长了轴承的使用寿命，且烧结温度较低，制备工艺简单，加工成本较低。
