| Abstract: | 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. |
