主　　题：friction stir processing aluminum/copper composite plate interface repairing mechanical properties 

摘      要：Multi-pass friction stir processing(M-FSP)was performed to repair the interface defects of AA5083/T2 copper explosive composite *** interface morphology and its bonding mechanism were *** results show that higher rotation speed and lower transverse speed produce more heat generated during *** 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/***,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.
