Abstract : Ceramic-to-metal seals and joints are assuming increasing importance in today's technology, and it is safe to predict that their uses will increase in the future as the advantages of ceramics as construction materials are realized. For example, when the first space station is established in outer space, ceramic-to-metal joints will play a significant role in its construction and operation. Nuclear- and solar-power devices will probably be used to provide energy, and ceramic-to-metal joints will be needed in the equipment that converts nuclear and solar energy to electrical power. Similarly, ceramic coating may be used to provide the emissivity required to control and maintain the proper temperature level within the space station structure. The performance of the space vehicles now depends on the ability of ceramic-to-metal joints to provide strength, erosion resistance, and high-temperature protection where needed.
