Popis: This paper reports on the development of Diffusion Braze Repair (DBR) techniques for service damaged turbine engine nozzle guide vanes (NGVs), made from cobalt and nickel-base superalloys. A description of the work undertaken by Vac-Aero in collaboration with the Institute for Aerospace Research of the National Research Council on qualification of the repair techniques for aero engine applications is also provided. This qualification work included bench testing of material test coupons as well as accelerated endurance testing of repaired aero engine parts under simulated service conditions in a burner rig. The results of stress rupture and burner rig tests indicate that Diffusion Braze Repair is an attractive and viable alternative to component replacement.
