POWDER PARTICLES AND MICRO-SPHERES METALLIZATION METHOD OUT OF GAS PHASE AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2007 - IPC B22F1/00 C23C16/00 

FIELD: powder metallurgy, namely processes and equipment for metallization of powder particles and micro-spheres out of gas phase, for example by decomposition of organometallic compounds.

SUBSTANCE: method comprises steps of pouring powder to be metallized into one chamber of reactor 1 for heating powder till decomposition temperature of easily volatile metal compound; turning reactor 1 by 180° around its rotation axis in order to pour powder from one chamber to other chamber of reactor through reaction zone; realizing powder pouring process at forced agitation of powder volume at outlet of chamber; then dispersing powder in reaction zone. Chambers of reactor are mutually coupled by means of transition insert 2 mounted in backup rolls with possibility of rotation. Each chamber is in the form of truncated cone and it is connected with transition insert 2 by its small base. Transition insert 2 is in the form of splitter with cone surface. Cross section area of splitter increases towards place of connection with pipelines 5. Pipelines 5 designed for inlet and outlet of gas-phase vapor are used also as supporting shafts. Agitator 7 is mounted at outlet of chamber; each chamber is provided with its own heater 3. Pipeline 4 for inlet of easily volatile compounds is cooled by water.

EFFECT: possibility for providing highly homogenous coating of powder materials and micro-spheres out of gas phase.
