Abstract:
Because the diffusion brazing invalidation of the titanium alloy injector occurred in an engine hot test, an improvement research of the injector welding configuration and parameters was performed based on the failure analysis by scanning electron micrograph, metallographic analysis and XPS methods. The results of simulation and test show that intensity and consistency of the improved diffusion welding are evidently enhanced.
