Abstract
A process for joining or coating carbon-carbon composite components. For joining such components, surfaces of two components are prepared so that they match. An interlayer comprised of a material having a melting point in excess of 2500.degree. F. is sandwiched between the two surfaces and the assembly is held together under compression while it is heated to a temperature sufficient to melt the interlayer material or to a temperature sufficient to cause interdiffussion between the interlayer and the carbon-carbon composite material. In a preferred embodiment of this invention the interlayer material is a carbide former. For example, if zirconium is chosen as the interlayer material, a joint can be prepared at a temperature of 3400.degree. F. which will retain its strength to temperatures in excess of 4350.degree. F. If the second surface is a removable backing, the interlayer provides a coating of the surface of the carbon-carbon composite component.
