DEVICE FOR PLASMOCHEMICAL SEDIMENTATION FROM VAPOR PHASE OF WINDING TYPE Russian patent published in 2009 - IPC C23C16/44 C23C16/04 C23C16/22 C23C16/54 

FIELD: metallurgy.

SUBSTANCE: invention relates to device for plasmochemical sedimentation from vapor phase of winding type for formation of coating layer on film. Film (22) is kept between couple of mobile drums, located at side of outlet and side of inlet of sedimentation section (25) relative to direction of movement of film (22). Then film (22) is forced to move linear into place of sedimentation. Distance between lattice for dispersion (37) and film (22) is kept constant, and quality of layer is homogeneous. Film is heated by means of metallic strip (40), simultaneously moving at reverse side of film. Movable drums are lifted from the position of sedimentation into position of self-cleaning, and film (22) can be separated from lattice for dispersion (37). Self-cleaning can be implemented on the way of sedimentation on film, closing slot of mask (51) by shutter (65) and, thereby, preventing dispersion of cleaning gas.

EFFECT: invention provides receiving of layer's high quality ensured by feeding of reactionary gas evenly to sedimentation area of film, and it is possible to implemented self-cleaning process of sedimentation area on the way of sedimentation on film.
