试验采用Ti51ZrNiCu钎料，研究其在TA1/TC4异质界面的反应润湿过程，使用扫描电子显微镜(SEM)、能谱分析仪(EDS)及润湿角测量仪等分析方法研究了不同表面的润湿界面组织结构，并总结了试验参数对组织结构和润湿能力的影响规律. 而后进行了填缝试验，用于衡量Ti51ZrNiCu钎料在TA1/TC4异质界面的润湿铺展能力，总结了钎料填充经验公式. 结果表明，在试验参数为935 ℃/3 min的条件下，TiZrNiCu钎料对TA1和TC4母材填充能力可简化为经验公式：h = 4 000/a，其中钎缝间隙a的单位为μm，爬升高度h单位为mm.

Ti51ZrNiCu filler alloy was used to study the reactive wetting process on TA1/TC4 heterogeneous interface. The interfacial microstructure of different surfaces was studied by scanning electron microscope(SEM), energy dispersive spectrometer(EDS) and wetting angle measuring instrument. And the influences of experiment parameters on interfacial microstructure and wettability were summarized. The filling experiment was finished to evaluate the wetting and spreading ability of TiZrNiCu on TA1/TC4 heterogeneous interface. The empirical equation of filling experiment was summarized. The empirical equation, h = 4000/a, was used to assess filling ability of TiZrNiCu on TA1/TC4 heterogeneous interface at 935 ℃ for 3 min. In this empirical equation, the unit of brazing gap a is μm, and the unit of climbing height h is mm.
