摘要：Multi-pass friction stir processing (M-FSP) was performed to repair the interface defects of AA5083/T2 copper explosive composite plates. The interface morphology and its bonding mechanism were explored. The results show that higher rotation speed and lower transverse speed produce more heat generated during FSP. The defect-free and good mechanical properties of the AA5083/T2 copper composite plate can be obtained under the condition of the rotation speed of 1200 r/min, the transverse speed of 30 mm/min and the overlap of 2/24. Moreover, M-FSP changes the interface bonding mechanism from metallurgical bonding to vortex connection, improving the bonding strength of composite plate, which can guarantee the repairing quality of composite plates. ? 2021 The Nonferrous Metals Society of China
