Carbon ceramic brake disc and preparation method thereof
The invention relates to a carbon-ceramic brake disc and a preparation method thereof, and the carbon-ceramic brake disc comprises 30-50 wt% of a carbon fiber preform, 1-10 wt% of silicon, 0.1-3 wt% of boron, 0.1-2 wt% of tungsten, and the balance of silicon carbide and inevitable impurities based on 100% by mass. By adding a certain proportion of boron and tungsten into the carbon-ceramic brake disc and utilizing the synergistic effect of boron and tungsten, nanoscale tungsten boride is generated through high-temperature reaction in a carbon-rich atmosphere, the graphitization degree and wear resistance of the carbon-ceramic brake disc can be effectively improved, and the service life of the carbon-ceramic brake disc is prolonged. The preparation method is simple and convenient, and is suitable for large-scale production.
本发明涉及一种碳陶刹车盘及其制备方法，以质量百分比为100％计，所述碳陶刹车盘包含30‑50wt％的碳纤维预制体、1‑10wt％的硅、0.1‑3wt％的硼以及0.1‑2wt％的钨，余量为碳化硅以及不可避免的杂质。通过在碳陶刹车盘中添加一定比例的硼元素和钨元素，并利用硼和钨的协同作用，在富碳气氛下高温反应生成纳米级的硼化钨，可以有效提高碳陶刹车盘的石墨化度和耐磨性，延长其使用寿命。本发明所述制备方法简单方便，适合大规模生产。
