Abstract
The results of using a forevacuum plasma electron source for obtaining gradient metal-ceramic materials are presented. The sintered material was located in a graphite crucible, which was heated by a wide electron beam to the temperature of 100 degrees lower sintering temperature for a given material. The sintering was carried out using a narrow-focused beam directed to the surface of the cermet powder. It is shown that when a coarse-grained aluminum oxide powder and fine-dispersed titanium powder are used, quite brittle samples are obtained. In the same time using of fine powder of aluminum and titanium, as well as their mixtures, allow to create a multilayer metal-ceramic sample with a variable composition, from titanium to aluminum.
