METHOD AND DEVICE FOR ARTICLE METALISING BY LIQUID-VAPOUR PROCESS AND CONTROL OVER PERMEABILITY OF BUTTS BETWEEN RETORT PARTS IN SAID DEVICE Russian patent published in 2015 - IPC C23C14/24 C23C14/56 B22F3/26 

FIELD: process engineering.

SUBSTANCE: set of invention relates to production of articles from composites with carbide-metal matrix by vapour-fluid phase metalising. This process includes placing the porous blank and crucible with metal in closed retort and their heating to get metal vapours and to ensure metal mass transfer into blank material pores by metal vapour condensation, intermediate cooling, isothermal curing at maximum temperature of metalising and final cooling. Metalising is effected with the help of retort consisting of separated parts and by adjustment of permeability of butts between retort parts. Metal mass transfer into material pores is effected at decreased permeability of retort parts butt by their covering by fusible gate while final cooling is performed at higher permeability of retort parts butts by removal of overlapping butt of fusible gate. Invention covers the device for process implementation and process of permeability adjustment.

EFFECT: uniform metalising, reproducible results of metalising, longer life of retort.
