The invention relates to a molybdenum-aluminum-boron ceramic particle reinforced copper-based composite material, a preparation method thereof and a pantograph slide plate, and belongs to the technical field of copper-based alloys. The molybdenum-aluminum-boron ceramic particle reinforced copper-based composite material is composed of a copper alloy matrix and molybdenum-aluminum-boron ceramic particles dispersed in the copper alloy matrix. The mass ratio of the copper alloy matrix to the molybdenum-aluminum-boron ceramic particles is (70-90): (10-30). According to the copper-based composite material, the molybdenum-aluminum-boron ceramic particles, tin, aluminum and iron have a synergistic effect, so that the copper-based composite material keeps high conductivity, the hardness of the copper-based composite material is moderate, a stable friction coefficient is kept, the copper-based composite material is used as a pantograph slide plate material, the sliding damage degree to a matched auxiliary wire is small, and the problems that a pantograph slide plate for a high-speed railway is poor in conductivity, insufficient in lubricating performance, prone to arcing and the like can besolved.
本发明涉及一种钼铝硼陶瓷颗粒增强铜基复合材料及其制备方法、受电弓滑板,属于铜基合金技术领域。本发明的钼铝硼陶瓷颗粒增强铜基复合材料,由铜合金基体和分散在铜合金基体中的钼铝硼陶瓷颗粒组成;铜合金基体和钼铝硼陶瓷颗粒的质量比为70~90:10~30。本发明的铜基复合材料,钼铝硼陶瓷颗粒以及锡、铝、铁之间协同作用,不仅使铜基复合材料保持较高的电导性,还能使铜基复合材料的硬度适中并保持稳定的摩擦系数,作为受电弓滑板材料,对配副导线的滑动损伤程度较小,可以解决高速铁路用受电弓滑板导电性能差,润滑性能不足且易起弧等问题。
