摘要：

The possibility of creating ceramic-metal joints by electron beam welding is considered. The welding of alumina ceramic to aluminum and titanium was performed in the fore-vacuum pressure range (5-20 Pa) using a plasma electron source. The structure and composition of the ceramic-metal transition layer are investigated. It is shown that the transition-layer thickness exceeds substantially the microroughness size of the initial ceramic, which confirms that intermixing of materials, i.e., welding, has occurred. The depen-dence of breaking strength of the obtained joints on the electron-beam power is measured. A sharp difference in the strength depending on the metal selection is found: the ceramic-aluminum weld strength is an order of magnitude higher than the strength of the ceramic-titanium system. © Pleiades Publishing, Ltd., 2012.
