研究了超声振动对30vol%Al2O3增强Al-Cu合金基复合材料在空气气氛中可焊性的影响。结果表明，在液滴形成和钎焊试验中，超声振动使液体填料在非润湿基体金属上具有优异的铺展能力。通过从基底金属去除氧化物膜来改善润湿性，在此期间，填料元素在复合材料中的先前扩散产生部分熔化起重要作用。随着焊接时间的延长，接头强度显著增加，在超声振动3 s后达到与钎料相等的值。超声波焊接的使用是一种可能的解决方案，在连接高度增强与陶瓷颗粒的铝合金的问题。(C)2011爱思唯尔有限公司保留所有权利。
The effect of ultrasonic vibration on the solderability of a 30 vol% Al2O3 reinforced Al-Cu alloy matrix composite in an air atmosphere was investigated. The results showed ultrasonic vibration gave the liquid filler an excellent ability to spread on the non-wetting base metal in both drop formation and soldering tests. Wetting was improved by removing the oxide film from the base metal, during which previous diffusion of the filler elements in the composite material producing partial melting played an important role. The joint strength increased significantly with soldering time, reaching a value equal to that of the filler metal after 3 s of ultrasonic vibration. The use of ultrasonic soldering is a possible solution to the problems in joining aluminum alloys highly reinforced with ceramic particles. (C) 2011 Elsevier Ltd. All rights reserved.
