Abstract
Abradable honeycomb sealing systems are essential for gas turbine efficiency. Experimental data on the rubbing performance of Haynes 214 metal sheets brazed with the nickel-chromium-silicon filler metal BNi-5 is presented. The brazing layer in the double foiled honeycomb sections turned out to have a major impact on rubbing behavior. Damage on the rotor was analyzed with a large chamber scanning electron microscope and energy-dispersive X-ray spectroscopy. The results demonstrate a significant influence of the brazing process on the mechanical properties, especially after exposure to 1000 °C. A hard aluminum nitride phase formed in the brazed metal sheets can cause severe damage to the rotor.
