    摘要： Embodiments of laminated stator cores (66) suitable for usage in high temperature applications are provided, as are embodiments of methods (10) for manufacturing high temperature laminated stator cores. In one embodiment, the method includes obtaining (12) a plurality of coated laminates (16) each comprising a laminate over which a coating precursor layer (34) is formed. The coating precursor layer contain inorganic dielectric particles having a softening point. The plurality of coated laminates are arranged (40) in a laminate stack (58), which is then fired (54) at temperatures equal to or greater than the softening point of the inorganic dielectric particles. During firing, a compressive force is applied to the laminate stack sufficient to consolidate the inorganic dielectric particles into a plurality of coherent interlaminate dielectric layers (72) electrically insulating and bondingtogether the plurality of coated laminates as the high temperature laminated stator core.

    摘要： A method for forming a protective coating on a surface of a ceramic substrate includes combining a rare-earth oxide, alumina, and silica to form a powder, etching the surface of the ceramic substrate, applying the powder on the etched surface in an amount of from about 0.001 to about 0.1 g/cm 2 to reduce capture of bubbles from off-gassing of the ceramic substrate, heating the powder for a time of from about 5 to about 60 minutes to a temperature at or above the melting point such that the powder melts and forms a molten coating on the surface that has a minimized number of bubbles, and cooling the molten coating to ambient temperature to form the protective coating disposed on and in direct contact with the surface of the ceramic substrate such that the protective coating has a thickness of less than about 1 mil.

    摘要： Methods (60) for forming sintered-bonded high temperature coatings (38, 110) over ceramic turbomachine components (46, 110) are provided, as are ceramic turbomachine components (22) having such high temperature coatings formed thereover. The method includes the step or process of removing (62) a surface oxide layer (74) 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 (66) to the treated surface. The first layer of the coating precursor material is then heat treated (68) 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.
