摘要：
Alumina borate whisker reinforced aluminium metal matrix composites were liquid bonded in air. The liquid filler metal of a Zn-Al eutectic alloy could get into the clearance between composites couples by the action of ultrasonic capillarity. The bond/composite interface was eroded, so that a rough interface formed and the oxide film could be removed completely under the action of ultrasonic vibration for 3 s. The shear strength of the bond increases with ultrasonic time. A removal model for the oxide film on the composites during ultrasonic aided liquid bonding was established.
