摘要:
A ceramic article includes a flexible backing selected from paper, woven fabric, non-woven fabric, polymeric films, metal foils, and combinations thereof. A green ceramic layer is on a first side of the flexible backing, wherein the green ceramic layer includes a ceramic material and a polymeric binder. A major surface of the green ceramic layer includes a pattern of features.

The disclosure describes techniques for forming a surface layer of an article including a CMC using a cast. In some examples, the surface layer includes three-dimensional surface features, which may increase adhesion between the CMC and a coating on the CMC. In some examples, the surface layer may include excess material, with or without three-dimensional surface features, which is on the CMC. The excess material may be machined to remove some of the excess material and facilitate conforming the article to dimensional tolerances, e.g., for fitting the article to another component. The excess material may reduce a likelihood that the CMC (e.g., reinforcement material in the CMC) is damaged by the machining.

A multi-layered cladding material including a ceramic matrix composite and a metallic material, and a tube formed from the cladding material. The metallic material forms an inner liner of the tube and enables hermetic sealing of thereof. The metallic material at ends of the tube may be exposed and have an increased thickness enabling end cap welding. The metallic material may, optionally, be formed to infiltrate voids in the ceramic matrix composite, the ceramic matrix composite encapsulated by the metallic material. The ceramic matrix composite includes a fiber reinforcement and provides increased mechanical strength, stiffness, thermal shock resistance and high temperature load capacity to the metallic material of the inner liner. The tube may be used as a containment vessel for nuclear fuel used in a nuclear power plant or other reactor. Methods for forming the tube comprising the ceramic matrix composite and the metallic material are also disclosed.

The aim of the invention is to improve the bond between the oxide ceramic and the veneer material and to increase the durability of said bond. According to the invention, an adhesion promoter (mixture of silicate ceramic and quartz) is applied as a sol to a main body that is to be veneered and that has not yet been densely sintered, the main body being made of oxide ceramic or starting materials thereof. The main body is then sintered to a final state together with the worked-in adhesion promoter, and afterwards the veneer material is applied. The invention is used, for example, to produce dental crowns and bridges having a high load-bearing capacity.
