本工作的目的是描述和讨论的基本问题，在氧化铝与铜的CuAgTi合金的反应钎焊。用于将Ti带到CuAg钎焊的方法使得钎焊中的Ti浓度能够在很大程度上变化（从0.8至6 wt.%）。然后可以研究该参数对界面化学和接头微观结构的影响，以及对钎焊接头的机械性能的影响，其特征在于通过拉伸试验。还将通过反应钎焊处理的金属/氧化铝接头的机械强度与使用标准金属化工艺获得的数据进行了比较。
The purpose of this work was to describe and discuss the fundamental issues involved in reactive brazing of alumina to copper by CuAgTi alloys. The method used to bring the Ti to the CuAg braze enabled the Ti concentration in the braze to be varied to a large extent (from 0.8 to 6wt.%). It was then possible to study the effects of this parameter on the interfacial chemistry and joint microstructure, as well as on the mechanical performance of the brazing joints, characterized by tensile tests. The mechanical strength of metal/alumina joints processed by reactive brazing was also compared with data obtained using a standard metallization process.
