Abstract
Abradable honeycomb sealing systems are widely used in turbines to improve efficiency and thus reduce carbon dioxide emissions. The honeycomb sealing systems are produced by brazing together nickel-based superalloy sheets with a nickel-based brazing metal. This investigation aimed to generate data on the mechanical performance of Haynes 214 metal sheets brazed with the nickel–chromium-silicon filler metal BNi-5 (71 wt.% Ni, 19 wt.% Cr, 10 wt.% Si). Tensile properties of brazed metal sheet composites are tested. Interdiffusion zones and hard particles with high chromium contents are observed along the brazed joint. Even a very thin brazing layer reduces the ductility considerably.
