METHOD OF MANUFACTURING ALUMINIUM PARTS Russian patent published in 2017 - IPC C23C28/00 C22F1/04 C09D5/08 

FIELD: technological processes.

SUBSTANCE: forming a part from a workpiece having applied on its surface a thin-film pre-treatment layer and a coating-lubricant, applying the adhesive over the thin-film pre-treatment layer and the lubricating coating to the connecting portion of the part, applying a cleaner to the parts of the part to remove said pretreatment layer and coating - Lubricants from its surface, except for the connecting part of the part with glue applied, and then applied to the part of the conversion coating by immersion in the bath. The apparatus includes a device for applying the adhesive to the pretreatment layer and coating-lubricant on the connecting portions of the workpiece, a first immersion bath for applying to the cleaner part to remove the pretreatment layer and the lubricating coating from the surface of the part, except for the connecting portion of the glued part, and The second immersion bath for applying to the detail of the conversion coating.

EFFECT: excellent ductility, durability of the bonding compound and corrosion characteristics for a vehicle made of aluminium at large production volumes.
