摘要
采用Al66Si5Cu26Zn2Ti1钎料真空钎焊65vol%Si CP/Al复合材料与20vol%SiCP/Al复合材料,并对钎焊接头进行了显微组织分析、能谱分析、剪切强度测试及气密性分析。结果表明:Al66Si5Cu26Zn2Ti1钎料能够实现镀镍65vol%SiCP/Al复合材料与20vol%SiCP/Al复合材料的钎接;Ti阻止了SiC与Al的界面反应;结合生产效率和生产成本,570℃×20 min为最优工艺。
65vol% SiCP/Al composite and 20vol% SiCP/Al composite were solder vacuum brazed by using Al66Si5Cu26Zn2Ti1. By SEM, EDS analysis. The microstructure, EDS analysis, shearing strength and gas tightness of the welded joint were studied. The results show：Al66Si5Cu26Zn2Ti1can achieve the connection between 65vol% SiCP/Al composite with nickel chemical-plating on the surface and 20vol% SiCP/Al composite. Ti can prevent the interfacial reaction of SiC and Al.Combined with the production efficiency and cost, the process of 570℃×20 min is the optimal process.
