The present invention provides for a method to reduce the strength of the honeycomb of a jet turbine stator, increasing its machinability, with a resultant reduction in measured peak tooth temperature, while maintaining or even improving its high temperature capability, so as not to limit its operating environment. The air seal functionality is unaffected, and even improved in some instances. The machinability of the honeycomb is increased by using a light element diffused into the honeycomb ribbon to produce the effect of reducing its strength and ductility while maintaining the environmental resistance needed. The present invention also includes the stator honeycomb produced by the foregoing method.
A method for producing a honeycomb seal having reducing cutting energy and improving the temperature capability for use in a turbine engine, comprising the steps of:
The method of claim I wherein the step of exposing the honeycomb seal to the diffusible element includes applying the diffusible element to the honeycomb seal using an adherable tape having the diffusible element.
A honeycomb seal having reducing cutting energy and improving the temperature capability for use in a turbine engine, produced by the steps of:
A ribbon material for use as a stationary portion of a labyrinth seal used in a turbine engine, the material comprising:
