Carbon ceramic brake disc and preparation method thereof
The invention belongs to the technical field of carbon-ceramic brake discs, and particularly relates to a carbon-ceramic brake disc and a preparation method thereof. According to the preparation method of the carbon ceramic brake disc, after carbon densification is carried out on a carbon fiber preform through chemical vapor deposition and before siliconizing is carried out, glue distribution treatment is carried out on the surface of the C/C brake disc through a glue material, and then heat treatment and mold pressing treatment are carried out, so that the glue material can permeate into the C/C brake disc; the inorganic powder (silicon carbide powder and/or carbon powder) and the C/C brake disc are bonded into a whole through the liquid resin, then siliconizing treatment is carried out, the defect that white spots appear on the disc face of the obtained carbon ceramic brake disc can be effectively avoided, and therefore the obtained silicon carbide ceramic coating is not prone to falling off and long in service life. Meanwhile, according to the preparation method, only glue distribution, heat treatment and mold pressing treatment need to be conducted on the surface of the C/C brake disc, and the preparation cost is low.
本发明属于碳陶刹车盘技术领域，具体涉及一种碳陶刹车盘及其制备方法。本发明提供了一种碳陶瓷刹车盘的制备方法，在通过化学气相沉积对碳纤维预制体进行碳增密后，在进行渗硅之前，通过胶料对C/C刹车盘表面进行布胶处理，然后通过热处理和模压处理，能够使胶料渗入到C/C刹车盘内部，通过液态树脂将无机粉体(碳化硅粉和/或碳粉)与C/C刹车盘粘接成为整体，然后再进行渗硅处理，能够有效避免得到的碳陶刹车盘盘面出现白色斑点缺陷，从而得到的碳化硅陶瓷涂层不易脱落，使用寿命长。同时，本发明提供的制备方法仅仅需要对C/C刹车盘表面进行布胶、热处理和模压处理，制备成本低廉。
