| 摘 要： | 在大气中对复相Al2O3基陶瓷与钢进行了直接钎焊连接。采用扫描电镜、能谱分析和X射线衍射等测试手段，对接头的微观组织形貌、特征点的成分和界面反应产物等进行了分析研究。结果表明，在一定的工艺条件下，可以实现复相Al2O3基陶瓷／钢在大气中的直接钎焊连接。复相Al2O3基陶瓷／钢的接合为元素的扩散和界面反应的综合结果，界面反应产生的新相主要为复合化合物FeWO4。

| Abstract: | The Al_2O_3-based ceramic composite/steel joint by brazing in air was investigated. The interfacial microstructure, chemical composition and interfacial reaction were studied by scanning electron micrograph (SEM), energy spectrum analysis (EDS) and X-ray diffraction (XRD). The results indicate that Al_2O_3-based ceramic composite/steel could be directly brazed in air. The joint of Al_2O_3-based ceramic composite/steel resulted from element diffusion and interfacial reaction. The new reactive phase in interface was FeWO_4. |
