Brazing ZTA ceramic to TC4 alloy using Ag-Cu filler metal
-
摘要: 使用Ag-Cu钎料钎焊ZTA陶瓷与TC4钛合金，利用扫描电子显微镜(SEM)、能谱分析仪(EDS)和X射线衍射仪(XRD)等设备分析了钎焊接头界面组织，阐明了反应机理，并研究了钎焊温度对接头界面组织和力学性能的影响. 结果表明，钎焊接头的界面结构为ZTA陶瓷/TiO+Ti3(Cu,Al)3O/Ag(s,s)/Ti2Cu3/TiCu/Ti2Cu/α+β-Ti/TC4合金. 随着钎焊温度的升高，钎缝中Ag基固溶体层变薄，Ti-Cu金属间化合物层变厚，当钎焊温度达到890 ℃时，Ti-Cu金属间化合物几乎占据整了个钎缝区域. 随着温度的升高，接头抗剪强度先增大后减小，在钎焊温度为890 ℃时，接头的室温抗剪强度达到最大值，其值为43.2 MPa.Abstract: Ag-Cu filler was used to braze ZTA ceramic and TC4 alloy. Scanning electron microscopy, energy disperse spectroscopy and X ray diffraction were used to identify the interfacial microstructure and the reaction mechanism of the joints was clarified. The typical interfacial microstructure was ZTA ceramic/TiO+Ti3(Cu,Al)3O/Ag(s,s)/Ti2Cu3/TiCu/Ti2Cu/α+β-Ti/TC4 alloy. The experiments were carried at the brazing temperature from 810 °C to 910 °C. The results indicated that as the brazing temperature increased, Ag-based solid solution layer thinned and Ti-Cu intermetallic compound layers thickened. When brazed at 890 °C for 10 min, Ti-Cu intermetallic compounds occupied almost the entire brazing area, and the shear strength of the joints reached the highest value of 43.2 MPa.
