  • Optimized high purity coating for high temperature thermal cycling applications
    Publication number: 20070082131
    Abstract: The invention is directed to a blended material and method for obtaining thermal barriers for high temperature cycling applications that have both high sintering resistance to achieve a high service lifetime and low thermal conductivity to achieve high operating temperatures. These materials are additionally suited for use in high temperature abradable (rub seal) coatings. The invention provides desired coating structures so that the changes in the coating microstructure over the in-service lifetime are either limited or beneficial.

  • Thermal spray feedstock composition
    Publication number: 20060213326
    Abstract: The invention relates to a thermal spray feedstock composition that employs free flowing agglomerates formed from (a) a ceramic component that sublimes,(b) a metallic or semi-conductor material that does not sublime and (c) a binder. The invention also relates to a method for preparing the agglomerates and a method for preparing ceramic containing composite structures from the agglomerates.
