随着碳铜复合材料的性能不断改进，其应用领域越来越广，对碳铜复合材料的性能、尺寸及形状提出更高要求，促使了碳铜复合材料制备工艺的改进。热等静压浸渍是目前制备碳铜复合材料的先进工艺，在高速铁路弓网系统受电弓滑板中已有少量应用，但仍存在一些问题：With the continuous improvement of the performance of carbon-copper composite materials, its application fields are becoming wider and wider, and higher requirements are put forward for the performance, size and shape of carbon-copper composite materials, which promotes the improvement of the preparation process of carbon-copper composite materials. Hot isostatic pressing impregnation is currently an advanced process for preparing carbon-copper composite materials. It has been used in a small amount in pantograph slides of high-speed railway pantograph-catenary systems, but there are still some problems:
1)浸渍压力较低，对于壁厚较厚的产品，浸渍深度难以满足要求，如中国专利号No.201010106908.2的发明专利提供了一种铜/石墨复合材料及其制造方法，浸渍时的压力为60～80MPa；1) The impregnation pressure is low. For products with thicker walls, the impregnation depth is difficult to meet the requirements. For example, the invention patent of Chinese Patent No. 201010106908.2 provides a copper/graphite composite material and its manufacturing method. The impregnation pressure is 60～80MPa;
2)无法连续生产，效率低、成本高，如中国专利号No.200710158757.3的发明专利提供了一种炭石墨热等静压浸银工艺，需要在热等静压浸渍完成后冷却至100℃以下出炉，且银熔液凝固后包裹在炭基体周围，需要通过机械加工处理才能得到产品。因此，为了适应各行业对大尺寸、低成本碳铜复合材料的高性能要求，需对热等静压浸渍工艺进行改进。2) Continuous production is impossible, with low efficiency and high cost. For example, the invention patent of Chinese Patent No. 200710158757.3 provides a carbon graphite hot isostatic pressing silver immersion process, which needs to be cooled to below 100°C after the hot isostatic pressing is completed. Out of the furnace, and the silver melt is solidified and wrapped around the carbon matrix, which requires mechanical processing to obtain the product. Therefore, in order to meet the high-performance requirements of large-scale, low-cost carbon-copper composite materials in various industries, the hot isostatic pressing impregnation process needs to be improved.
