ABSTRACT:
Within gas turbine engines10it is necessary to provide fixed vanes which comprise an aerofoil in the gas flow through the gas turbine engine10. These vanes are subject to significant stressing. Therefore it is generally necessary to secure the vane at one end103through an appropriate bond such as brazing while at another end a friction damping response is achieved. By providing an anti-bonding layer it is possible to prevent a mechanical bond being formed at the friction damping end105. Furthermore, a tight fit can be emphasized by residual bonding material remaining after an attempted bonding process upon the anti-bonding layer.
