Carbon/carbon-silicon carbide tool, preparation method thereof and application of carbon/carbon-silicon carbide tool in liquid-phase siliconing of carbon-ceramic brake disc
The invention relates to the technical field of brake materials, and provides a carbon/carbon-silicon carbide tool, a preparation method of the carbon/carbon-silicon carbide tool and application of the carbon/carbon-silicon carbide tool in liquid-phase siliconizing of a carbon-ceramic brake disc. The method comprises the following steps: needling carbon fiber cloth and a carbon fiber net tire to obtain a tool prefabricated body, and coating a binder, curing, performing chemical vapor deposition densification, roughly machining and performing liquid-phase siliconizing to obtain the carbon/carbon-silicon carbide tool. The carbon/carbon-silicon carbide tool is in a cylinder shape with sawteeth at one end. The tool is made of carbon/carbon-silicon carbide, has the characteristics of high temperature resistance, abrasion resistance, corrosion resistance, high-temperature stability, high thermal conductivity, oxidation resistance and the like, is not prone to cracking and can be repeatedly used, and the production cost is reduced; moreover, the bottom of the tool is designed to be in a sawtooth shape, and during liquid-phase siliconizing, the situation that a large amount of silicon materials are stacked at the bottom of the brake disc, the silicon materials make contact with the brake disc and adhere to the brake disc can be avoided, so that the problem that a large amount of residual silicon slag adhere to affect the appearance of the disc face is solved.
本发明涉及刹车材料技术领域，提供了一种碳/碳‑碳化硅工装及其制备方法和在碳陶刹车盘液相渗硅中的应用。本发明将碳纤维布和碳纤维网胎进行针刺，得到工装预制体，再通过涂刷粘结剂、固化、化学气相沉积增密、粗加工和液相渗硅，得到碳/碳‑碳化硅工装；所述碳/碳‑碳化硅工装为一端具有锯齿的圆筒状。本发明的工装材质为碳/碳‑碳化硅，具有耐高温、耐磨损、耐腐蚀、高温稳定性、高导热性、抗氧化等特性，不易开裂，能够重复使用，降低了生产成本；并且，本发明将工装底部设计为锯齿状，在液相渗硅时，能够避免大量硅料堆积在刹车盘底部，导致硅料触碰刹车盘产生粘黏，从而解决了大量残余硅渣粘结、影响盘面外观的问题。
