摘要
采用 Ag-20Cu-5Ti 对 Al2O3P/Cu 基复合材料与 Nb 的钎焊性进行了初步探讨。研究表明,通过在钎料中加入活性元素 Ti,可以减少和消除钎缝中的 Al_2O_3P颗粒,避免 Al_2O_3P颗粒在钎缝中的聚集,实现离子共价键 Al_2O_3P 向类金属键 TiO 转化,从而提高钎缝基体与颗粒相之间的匹配性。
The brazing-ability of Al2O3P/Cu Base Metal Matrix Composite and Nb with AgCuTi filler metal was studied. The results show that through adding active element Ti to the filler metal, the Al2O3P grains in the brazing seam are decreased or eliminated, and the concentration of Al2O3P grains in the seam is avoided. The ionic bond Al2O3P is transformed in to metalloid bond TiO, so that the matching-ability of the brazing seam substrate and the grain phase is enhanced.
