DEVICE FOR VOLUME METALATION Russian patent published in 2016 - IPC C23C10/06 C23C14/14 

FIELD: metallurgy.

SUBSTANCE: device for volume metalation of blanks contains main heaters, installed around the outside retort, and additional heater to heat the crucibles with metal, internal closed retort with inside installed metalated blanks and crucibles with metal, flow reactor, thermal insulation out of porous coal-graphite materials and pneumatic-gas-vacuum system. Outside and internal retorts are made from parts located through height, and coaxially with each other with clearance. The outside retort has branch pipes for connection of the between retorts clearance with pneumatic-gas-vacuum system. Additional heater is located vertically at centre of the internal retort, made with possibility of assurance of uniform temperature field through its height, and located in build in bottom part of the internal retort tight protective sleeve out of heat-resisting material, around it through full height the crucibles with metal are installed. In particular case of the invention the crucibles with metal are made in form of semitoroids.

EFFECT: reduced length of metalation process with simultaneous rejects decreasing of both long, and made out of cermet parts.
