Silicon nitride composite material and preparation method thereof, and sealing ring and preparation method thereof
The invention belongs to the technical field of sealing ring processing, and particularly relates to a silicon nitride composite material and a preparation method thereof, and a sealing ring and a preparation method thereof. Boron nitride is added into silicon nitride, so that the overall hardness and wear resistance of the silicon nitride composite material can be remarkably improved; the binding agent is added into the silicon nitride, so that the binding effect can be enhanced, and various mechanical properties of the material are improved; the sintering aid is added, and a liquid phase can be provided in the sintering process, so that sintering is accelerated, and the sintering effect is improved. Compared with a traditional sintering process, through SPS plasma sintering or HPHT high-temperature and high-pressure sintering, the compactness and the mechanical property of the silicon nitride composite material can be remarkably improved while the sintering rate is increased.
本发明属于密封环加工技术领域，具体涉及一种氮化硅复合材料及其制备方法、一种密封环及其制备方法。本发明在氮化硅中加入氮化硼，可以显著地提高氮化硅复合材料的整体硬度与耐磨性；本发明在氮化硅中加入结合剂，可以起到增强结合效果，提升材料各项力学性能；本发明加入烧结助剂，可以在烧结过程中提供液相，从而加快烧结，提升烧结效果。本发明通过SPS等离子烧结或HPHT高温高压烧结，与传统的烧结工艺相比，提高烧结速率的同时，能够显著提升氮化硅复合材料的致密性和力学性能。
