    Effects of Copper Plating and Nickel Plating on Shear Strength of Vacuum Brazed Joints of SiCp/6063Al Composites

    • 摘要: 采用表面金属化工艺在60%SiCp/6063Al复合材料表面制备镀铜层和镀镍层, 然后对表面金属化处理前的复合材料进行真空加压钎焊, 研究了镀镍和镀铜对复合材料钎焊接头剪切强度的影响。结果表明: 复合材料表面镀层均与基体紧密结合; 在570 ℃的钎焊温度下, 随着保温时间延长, 钎焊接头的剪切强度逐步增大; 与表面镀镍及未镀金属的相比, 表面镀铜复合材料接头的剪切强度更高, 接头的剪切强度最高可达55.4 MPa, 且其剪切断裂发生在钎料层和复合材料内部; 镀镍会降低接头的剪切强度。
      Abstract: Using surface alloying technique, copper layer and nickel layer were deposited on the SiCp/6063Al composites with 60% volume fraction of SiC. Then, SiCp/6063Al composites before and after surface alloying were vacuum brazed respectively. The effects of copper layer and nickel layer on the shear strength of the brazed joints were studied. The results indicate that the two plating layers combined with base metal compactly. As prolonging the heat preservation time, the shear strength of the brazed joints rose synchronously at 570℃. The brazed joint of the composite with copper plating on surface had higher shear strength than that with nickel plating, and the top value hit 55.4 MPa. The shear fracture occurred on the inside of composites and in the brazing filler metal. Nickel plating decreased the shear strength of the joint.
