DEVICE FOR APPLICATION OF METALLIC COATINGS ON INTERNAL SURFACES OF FRICTION TYPE BEARINGS BY CVD-METHOD OF ORGANOMETALLIC COMPOUNDS Russian patent published in 2012 - IPC C23C16/06 

FIELD: metallurgy.

SUBSTANCE: device comprises a reactor with a heater and the ability to feed reaction gaseous medium inside it and removal of reaction products. The reactor is made up of two identical lids interconnected with the possibility of changing the distance between them and with its subsequent fixation and facing each other, having a common axis of symmetry and made with a hole along the axis of symmetry for the supply of reaction gaseous medium inside the reactor in one of them and a hole along the axis of symmetry for withdrawal of reaction products into the other one and made with a possibility of installing a graphite separation ring on the internal surface of each of them. There is a friction bearing installed on each splitter ring that can be alternated and that form a sealed area of metallisation by their inner cylindrical surfaces. Axis of symmetry of each friction bearing and each graphite splitter ring coincide and are located on the axis of symmetry of the lids.

EFFECT: device helps reduce irrational consumption of the reagents, increase application of metal into a coating and eliminate growth of scull on the inner surface of the reactor hot zone.
