Electron-Beam Sintering of Metalloceramic Materials in Medium Vacuum

Abstract

Ceramic-metal composite materials are promising materials of modern high-tech production. They combine a number of unique properties inherent in both ceramics (hardness, high strength, low creep) and metal (high thermal conductivity, electrical conductivity, resistance to shock loads). The current stage of technology development requires both improving methods for creating such materials and searching for new methods for their production. In the present work, the results of electron beam sintering of a ceramic-metal compact by a focused beam in the medium vacuum pressure range are presented. It is shown that by heating the compacts it is possible to achieve a uniform distribution of elements over the volume of the sintered sample.
