▎ 摘　　要

NOVELTY - Improving copper-based composite material strength and conductivity matching based on in-situ reaction, comprises (a) taking graphene oxide powder and chromium-containing copper-based alloy powder as raw material powder, uniformly mixing the raw material powder by grinding to obtain a mixed powder, and (b) performing plasma sintering of the mixed powder by in situ reaction, cooling to obtain the copper-based composite material with matched strength and electrical conductivity. USE - The method is useful for improving copper-based composite material strength and conductivity matching based on in-situ reaction. ADVANTAGE - The method improves the interface intensity between graphene oxide and chromium-containing copper base alloy, thus enables to prepare copper-based composite material with good conductive performance.
