Ceramic and metal article and method of making it

摘要

An article comprising a component of ceramic material and a metal component has a metal felt located between opposed faces of the two components, the metal felt being permanently joined to both the ceramic face and the metal face to join the two components together. The metal felt may be brazed to both components, the brazing alloy being one which chemically combines with the ceramic material. The brazing alloy may be in the form of a foil placed between the metal felt and each of the components, and the brazing may take place in a vacuum.
