    摘要： A ceramic composition for the repair of porous ceramic bodies comprises a ceramic material having cations which are reactive with phosphate ions, a source of reactive phosphate ions, and filler. An aqueous slurry of the ceramic composition is prepared and applied to the damaged region of a porous ceramic body. The slurry mixture is dried within the damaged region of the porous ceramic body and heated to bind the mixture together and to bond the mixture to the porous ceramic body within the damaged region. The method of the invention allows for the in situ repair of ceramic materials without removing them from their supporting structure and can be used in the repair of ceramic tiles for spacecraft and aircraft.

    摘要： A surface of a porous ceramic body is protected by binding ceramic particles entirely within the subsurface porosity of the body adjacent to the surface but not present as a separately identifiable surface layer. To produce such a protective layer, a slurry of a mixture of a ceramic powder and a silica-containing binding agent is first prepared. The slurry is impregnated into the surface of the body so that all of the slurry enters the porosity of the body and substantially none of the slurry resides on the surface. The slurry is dried in place, and the residual solids are fired to bind the ceramic powder to the interior walls of the porosity. Drying and firing can be accomplished at intermediate temperatures of about 700.degree.-1000.degree. F. using heat lamps, so that the surface protection can be accomplished without removing the ceramic body from a larger structure.

    摘要翻译： 多孔陶瓷体的表面通过将陶瓷颗粒完全结合在与表面相邻的本体的地下孔隙中而不作为单独可识别的表面层而被保护。 为了制备这样的保护层，首先制备陶瓷粉末和含二氧化硅的粘合剂的混合物的浆料。 将浆料浸渍到主体的表面中，使得所有的浆料都进入到主体的孔隙中，并且基本上没有浆料驻留在表面上。 将浆料干燥在适当的位置，并且将残留的固体烧制以将陶瓷粉末结合到孔隙的内壁。 干燥和焙烧可以在约700°-1000°F的中间温度下使用加热灯完成，从而可以在不从较大结构中去除陶瓷体的情况下实现表面保护。

    摘要： A ruddervator for an aerospacecraft. The ruddervator is formed by a plurality of airfoil sections nestably disposed in side by side fashion and supported by a pair of titanium box beam frame elements extending through central openings in each of the airfoil sections. Each airfoil section includes an oxide fiber/oxide matrix-based ceramic matrix composite (oxide-CMC) panel made up of multiple plies of oxide-CMC fabric which are fused over a rigid ceramic foam insulation member. The lower ends of the frame elements are secured to a transition component comprising a conventional torque box. The ruddervator can be manufactured with less cost and lower weight over previous ruddervator designs which require one or more large skin sections which are mechanically fastened to a substructure. The ruddervator of the present invention further minimizes fabrication costs by using a common design for the nesting airfoil sections so that a common female lay-up mold can be used for fabricating all of the airfoil sections.
