ZrO2-C fiber composite material and preparation method thereof
The invention discloses a ZrO2-C fiber composite material and a preparation method thereof. The ZrO2-C fiber composite material is prepared from the following components in percentage by mass: 12 to 18 percent of graphite, 3 to 5 percent of metal silicon powder, 0.3 to 1.2 percent of zirconium oxide fiber, 5 to 8 percent of binding agent, 0.1 to 1 percent of boron carbide, 22 to 28 percent of zirconium oxide fine powder and the balance of zirconium oxide coarse particles. The ZrO2 fiber is added into the ZrO2-C material, so that the thermal shock resistance of the ZrO2-C material is remarkably improved under the condition of not increasing carbon, the normal-temperature mechanical property and high-temperature property of the submersed nozzle are greatly improved, and the service life of the submersed nozzle is further prolonged.
本发明公开了一种ZrO2‑C纤维复合材料及其制备方法，包括以下质量百分比的组分：石墨为12‑18％，金属硅粉为3‑5％，氧化锆纤维为0.3‑1.2％，结合剂加入量为5‑8％，碳化硼0.1‑1％，氧化锆细粉为22‑28％，余量为氧化锆粗颗粒。本发明在ZrO2‑C材料中加入ZrO2纤维，在不增加碳的情况下显著的提高了ZrO2‑C材料的抗热震性能，极大的提升了浸入式水口的常温力学性能以及高温性能，进而延长了浸入式水口的使用寿命。
