Carbon ceramic brake disc with high surface graphitization degree
The invention provides a carbon-ceramic brake disc with a high surface graphitization degree. The carbon-ceramic brake disc with the high surface graphitization degree comprises a brake disc inner core and a high-graphitization surface layer, the brake disc inner core is coated with the highly graphitized surface layer, the graphitization degree of carbon in the highly graphitized surface layer is 70-95%, the thickness of the highly graphitized surface layer is 1-8 mm, and the graphitization degree of carbon in the brake disc inner core is 20-50%. The high-graphitization surface layer with the high graphitization degree is arranged on the surface layer area of the brake disc, the brake disc inner core is wrapped by the high-graphitization surface layer, the high-graphitization surface layer serves as a main contact area with a brake pad, the graphitization degree reaches up to 70%-95%, a complete friction film can be formed on the outer surface layer, the friction coefficient is more stable, and the service life of the brake disc is prolonged. And the friction performance of the brake disc can be improved.
本发明提供一种表面石墨化度高的碳陶刹车盘，所述表面石墨化度高的碳陶刹车盘包括一刹车盘内芯和一高石墨化表面层；所述高石墨化表面层包覆所述刹车盘内芯，所述高石墨化表面层中碳的石墨化度为70‑95％，所述高石墨化表面层厚度为1‑8mm，所述刹车盘内芯中碳的石墨化度为20‑50％。通过在刹车盘表层区域设置具有高石墨化度的高石墨化表面层，使其将刹车盘内芯包覆，高石墨化表面层作为与刹车片主要接触区，石墨化度高达70‑95％，其有利于外表面层形成完整的摩擦膜，是摩擦系数更稳定，有助于提升刹车盘的摩擦性能。
