摘要
Through the vacuum diffusion bonding for SiCp/ZLl01 aluminum matrix composite, the influence of bonding parameters on the joint properties was reported, with the aim to obtain optimal bonding parameters. The microstructureof joints was analyzed by means of optical microscope and scanning electron microscope in order to study the relationship between the macro-properties of joints and the microstructures. It was found that diffusion bonding couldbe used for bonding aluminum matrix composites successfully. Meanwhile, the properties of the matrix and the jointwere all affected by some defects such as the reinforcement aggregation in aluminum matrix composites made bystirring casting.
