DEVICE TO FORM NANOSTRUCTURED COATINGS WITH SHAPE MEMORY EFFECT ON SURFACE OF HOLLOW PARTS Russian patent published in 2015 - IPC C23C26/00 C23C2/34 C23C14/48 B82Y30/00 

FIELD: machine building.

SUBSTANCE: device contains vacuum chamber comprising hollow cooled casing with nozzles for air pumping out and argon supply, and lid, inside the chamber metal bath is installed, it is filled with liquid metal melt, around bath heating elements are installed, and between them and casing the heat protecting screens are installed to protect the vacuum chamber casing against overheating. Above the bath metal pipe is installed, it passes through the lid, and is secured in it with possibility of vertical movement. Pipe bottom end is made with possibility of securing to its bottom end of the hollow treated part with creation of the closed cavity, top end of the pipe projecting from the chamber is connected with lever installed on the lid for the pipe vertical movement. Outside the pipe there is nozzle to supply the cooling medium, inside the pipe there is hollow tube with nozzle for cooling medium drainage. Said device additionally contains a process module for ion cleaning of the treated part surface by creation of the glow discharge in the vacuum chamber. Source of ion implantation of metals is installed on casing of the vacuum chamber, and is connected with control box. Around the top end of the pipe with part the attachment secured on lid of the vacuum chamber is installed for surface-plastic deformation of the applied coating with creation of the nanostructured layer with shape memory effect.

EFFECT: increased strength, reliability of part coating, and reversible deformation and wear resistance.
