Abstract: A disclosed method of forming a ceramic article includes forming a pre-ceramic polymer article within a mold tool, and performing a first pyrolizing step on the initial pre-ceramic polymer article to form a ceramic article. The method further includes performing at least one pre-heat treatment polymer infiltration and pyrolizing (PIP) cycle on the ceramic article and an initial heat treatment cycle of the ceramic article after the at least one pre-heat treatment PIP cycle. Subsequent PIP cycles and heat treatment cycles are performed in combination to form a ceramic article including a desired density.

Abstract: The present disclosure relates to systems, methods and resins for additive manufacturing. In one embodiment, a method for additive manufacturing of a ceramic structure includes providing a resin including a preceramic polymer and inorganic ceramic filler particles dispersed in the preceramic polymer. The preceramic polymer is configured to convert to a ceramic phase. The method includes functionalizing inorganic ceramic filler particles with a reactive group and applying an energy source to the resin to create at least one layer of the ceramic phase from the resin.

Abstract: A gas turbine engine includes an airfoil having a core that has a first hardness and a surface on the core. The surface includes a plurality of geometric features that have a second, greater hardness. The geometric features define a surface porosity by area percent and a corresponding surface solidity by area percent. The surface includes a ratio of the surface solidity divided by the surface porosity that is 1.8 or greater. The geometric features and the ratio establish the surface to be hydrophobic, and the second, greater hardness and the ratio establish an erosion rate of the surface that is equal to or less than an erosion rate of the core under identical erosion conditions.
