- Few-layer graphene-enhanced Cu composite interlayer was prepared by CVD for brazing.
- Our obtained graphene could effectively impede the intensive Al-Cu eutectic reaction.
- The graphene contributed to strengthening the joint.
Contact Reaction Brazing of aluminum alloy 6061 using pure Cu nanoparticle interlayer usually encounters cracks and holes due to the intensive Al-Cu eutectic reaction. In order to solve these problems, here we report a new type of graphene-enhanced Cu composite (G-Cu) interlayer prepared by CVD to contact reaction braze aluminum alloy 6061. Results show that the G-Cu interlayer is conducive to retarding the intensive Al-Cu eutectic reaction. The average shear strength of the joint brazed with G-Cu interlayer reached 74Â MPa.
