摘　　要：某机压气机的空心可调节叶片组件是由钛合金材料TC4合金通过钎焊制成的,每个叶片都是由叶片主体和2个叶形板组成,叶片主体与叶形板之间采用钎焊连接。本文针对空心叶片组件的结构特点和使用要求开展了真空钎焊工艺研究,进行了钎料钎焊接头力学性能测试,同时,就钎焊热循环对TC4合金性能的影响、钎焊工艺路线程序、叶片焊后变形校正等工艺问题进行了深入研究,所确定的真空钎焊工艺程序可以钎焊出合格的可调叶片组件,钎焊质量稳定。The adjustable hollow blade assemblies of aviation engine compressor are made of TC4 titanium alloy by brazing. Each hollow blade consists of blade body and two metal sheets, the blade body and two metal sheets were joined by vacuum brazing. The paper tried to study vacuum brazing process based on the characteristic of hollow blade assembly structure and application requirements, including mechanics performance test on brazing joints, the influence of brazing heat cycle on TC4 titanium alloy performance, vacuum brazing process and hollow blade current form after brazing. The vacuum brazing process by studying suffices to meet requirements of hollow blade welding, and the quality of vacuum brazing seam could always keep stable.
