METHOD FOR RESTORATION OF THREE-DIMENSIONAL ART WORKS Russian patent published in 2010 - IPC B44C3/06 

FIELD: technological processes.

SUBSTANCE: damaged fragment is removed, new fragment is formed instead of damaged one and installed in place. After removal of damaged fragment, its base is processed, then strengthening metal rods are installed in base, and new fragment is formed instead of removed one in the following manner: powder containing plastic metals and/or their alloys is accelerated with heated compressed air till speed that exceeds minimum speed of sputtered material particles adhesive interaction, afterwards this flow is sent between rods onto surface of removed fragment, and initial layer is formed on it, which complies with base of removed fragment by configuration. By regulation of speed and angle of flow, and also distance from area of sputtering, on specified initial layer the whole volume of removed fragment is formed in layers between rods, afterwards object is maintained until final cooldown, correcting treatment of formed fragment is carried out, the whole piece is coated with protective layer from plastic metals and/or their alloys with application of gas dynamic sputtering.

EFFECT: invention makes it possible to create simpler and cheaper method of restoration, which reduction of time required for restoration of art work.
