中文摘要：

采用振动辅助下半固态扩散钎焊成功地焊接了SiCp/ZL101A复合材料。在连接过程中,施加了两次低频振动。第一次施加振动进行焊接时,钎料被加热至固液态。在此时钎料的半固态特征的获得是振动焊接成功的关键。半固态钎料的获得,可使钎料在焊接中不易被挤出。并且半固态钎料也加剧了钎料对基体表面的摩擦作用,从而促进了基体表面的氧化膜的破碎。然而,在一次振动焊接后的焊缝中的气孔限制了接头强度的提高。随后施加520℃的第二次振动,促使焊缝中的气孔被排除。此时接头的抗剪强度提高到160 MPa。

The semi-solid vibration brazing was successfully utilized in bonding of SiCp/ZL101A composites,in which twice vibration was introduced in brazing.When temperature was 375 ℃,the most of oxide film on the Al substrate was disrupted by the first vibration bonding.Filler metal with semi-solid character was the key to succeed in bonding of Al MMCs,which was hard to extrude out and helped to disrupt of oxide film on the substrate during vibration brazing.However,porosities in joint brazed by the first vibration ...
