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.
基于多道次搅拌摩擦加工(M-FSP)修复AA5083/T2紫铜爆炸复合板的界面缺陷,探讨界面形貌和界面结合机制。结果表明,搅拌摩擦加工过程中的高旋转速度和低前进速度会产生更多的热量。当旋转速度设定在1200 r/min,前进速度设定在30 mm/min,搭边量设定在2/24时,AA5083/T2紫铜复合板经多道次搅拌摩擦加工修复后无缺陷,且力学性能优良。多道次搅拌摩擦加工提高复合板的结合强度,其界面结合机制由冶金结合转变为旋涡状连接,为复合板的修复质量提供保障。
