The invention discloses a copper-graphite composite material, a pantograph slide plate and an electrified vehicle, and belongs to the field of materials. A pantograph slide plate on electrified vehicles such as a high-speed rail and the like is a key component of a power receiving element, is directly contacted with a contact network wire, guides current on a power transmission network in a static or sliding state, and transmits the current to a locomotive power supply system so as to maintain normal operation of an electric locomotive. The conductivity, wear resistance and strength of the pantograph slide plate are the most important factors for limiting the acceleration of the high-speed rail at present. Therefore, according to the copper-graphite composite material, the pantograph slide plate and the electrified vehicle, the problems that an existing train pantograph slide plate is low in mechanical strength, poor in impact toughness and serious in abrasion can be solved. According to the specific technical scheme, the copper-graphite composite material is formed by mixing, pressing and sintering metallized graphite powder and copper powder.

    本发明公开了一种铜‑石墨复合材料、受电弓滑板及电气化交通工具,属于属于材料领域。高铁等电气化交通工具上的受电弓滑板是受电元件的关键组成部分,受电弓滑板直接与接触网导线接触,在静止或滑动状态下将输电网上的电流引导下来,传输给机车供电系统,来维持电力机车正常运行。受电弓滑板的导电性能、耐磨性能及强度是目前限制高铁提速的最重要因素。因此,本发明提供的铜‑石墨复合材料、受电弓滑板及电气化交通工具,可以解决现有列车受电弓滑板机械强度低、冲击韧性差、磨损严重的问题。具体技术方案为,所述铜‑石墨复合材料由经过金属化处理后的石墨粉与铜粉混合、压制、烧结而成。
