Methods for forming sintered-bonded high temperature coatings over ceramic turbomachine components are provided, as are ceramic turbomachine components having such high temperature coatings formed thereover. In one embodiment, the method includes the step or process of removing a surface oxide layer from the ceramic component body of a turbomachine component to expose a treated surface of the ceramic component body. A first layer of coating precursor material, which has a solids content composed predominately of at least one rare earth silicate by weight percentage, is applied to the treated surface. The first layer of the coating precursor material is then heat treated to sinter the solids content and form a first sintered coating layer bonded to the treated surface. The steps of applying and sintering the coating precursor may be repeated, as desired, to build a sintered coating body to a desired thickness over the ceramic component body.

The present invention relates to a mesoporous film structure having ultra-large pores therein and a method of manufacturing the same. More particularly, the present invention relates to a mesoporous film structure having ultra-large pores therein and a method of manufacturing the same, in which a mesoporous film having ultra-large pores therein is formed on supports including various materials and having various shapes under chemically mild conditions. The size of the pores in the film is capable of being adjusted, and a patterned mesoporous structure is formed on the upper surface of the support rather than throughout the entire support.

A coated turbomachine component includes a ceramic component body having a principal surface. The component includes a high temperature coating. The high temperature coating includes a sintered coating body bonded directly to and intimately contacting the principal surface of the ceramic component body. The sintered coating body has a minimum porosity adjacent the principal surface and a maximum porosity at a location further from the principal surface, as taken along an axis orthogonal to the principal surface.
