Carbon-ceramic brake disc with double friction layers and preparation method of carbon-ceramic brake disc
The invention provides a carbon-ceramic brake disc with double friction layers, the carbon-ceramic brake disc comprises a base body layer and friction layers, the friction layers comprise a first friction layer and a second friction layer, and the first friction layer is located between the base body layer and the second friction layer. The content of silicon carbide in the first friction layer is 50-80%, and the content of silicon in the first friction layer is 20-50%; the content of silicon carbide in the second friction layer is 70-95%, and the content of silicon is 5-30%. The two friction layers are arranged, the outermost friction layer is the second friction layer, the second friction layer is high in silicon carbide content, large in thermal expansion coefficient, large in particle size and good in abrasion resistance, the inner friction layer is the first friction layer, the silicon carbide content of the first friction layer is lower than that of the second friction layer, and the first friction layer has the low thermal expansion coefficient; the problem of stress concentration generated by connection of the high silicon carbide friction layer and the base body is effectively relieved.
本发明提供一种具有双层摩擦层的碳陶刹车盘，所述碳陶刹车盘包括基体层和摩擦层，所述摩擦层包括第一摩擦层和第二摩擦层，所述第一摩擦层位于所述基体层和所述第二摩擦层之间。所述第一摩擦层中碳化硅含量为50‑80％，硅含量为20‑50％；所述第二摩擦层中碳化硅含量为70‑95％，硅含量为5‑30％。通过设置两层摩擦层，最外层摩擦层为第二摩擦层，第二摩擦层碳化硅含量高，热膨胀系数大，粒径大，具有良好的耐磨性，内层摩擦层为第一摩擦层，第一摩擦层的碳化硅含量比第二摩擦层的碳化硅含量低，具有较低的热膨胀系数，有效缓解了高碳化硅摩擦层和基体连接所产生的应力集中的问题。
