摘要：

In this work, the fabrication of graphene/Al laminate composites was achieved for the first time using the pulse current diffusion bonding method. A complete bonding interface without obvious defects was obtained under the conditions of 530 degrees C for 10min. The electron backscatter diffraction results revealed that the Al alloy recrystallized under the action of Joule heat, and fine grains were formed at the graphene/Al bonding interface. The transmission electron microscopy results showed that the bonding interface of graphene/Al was composed of graphene/amorphous layer + nanocrystalline MgO and Al2O3/MgO/Al. This research offers novel insights into the preparation of graphene/metal layer-stack composite materials.
