THE MANUFACTURING OF C/C COMPOSITE BRAKE DISK BY MEANS OF THERMAL GRADIENT CVD DENSIFICATION TECHNIQUE

利用自行研制的热梯度式炉系统探索了利用差温式 CVD增密技术制备高性能 C/ C复合刹车盘的可行性 ,研究了温度、气氛压力、气流量等参数对 CVD增密过程的影响及增密过程动力学特性 ,实现了在较短周期制取高密度 C/ C复合盘件 ,显示了该项技术工业应用的良好前景。

Using a new device developed in National Key Lab for Powder Metallurgy, the feasibility of the manufacturing of high performance C/C composite brake disk by means of thermal gradient CVD densification technique has been systematically investigated. The influence of the parameters, such as temperature, gas pressure, gas flow rate on CVD densification, as well as the charactoristics of dynamics during the densification process were studied, and the manufacturing of high dense C/C disk in a more short period was successfully realized, showing a bright prospect of this technique for commercial application.
