Through the vacuum diffusion welding SiCp/ZL101 aluminum with Ni interlayer, the effect of welding parameter and the thickness property of Ni on the welded joint was investigated, and the optimal welding parameters were put forward at the same time. The microstructure of joint was analyzed by means of optical-microscope, scanning electron microscope (SEM) in order to study the relationship between the macro-properties of joint and the microstructure. The results show that diffusion welding with Ni interlayer can be used for welding aluminum matrix composites SiCp/Z101 successfully. Under the welding parameters T=560degreesC, P=5 MPa, t=60 min, H=14 mum, the bonding strength of welded joint can up to 121 MPa. Moreover, the thickness of interlayer should match with the size of reinforced particles. If the thickness of interlayer is too thin, it would have no effect on the welded joint beneficially. If the thickness of interlayer is too thick, it would cause the "no-reinforcement zone" to appear.
