METHOD FOR PRECISION BRASSING OF SLEEVE-TYPE DETAIL AND FACILITY FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC C23C26/00 

FIELD: metallurgy, coating.

SUBSTANCE: invention concerns mechanical engineering field. Particularly it concerns method and structure of precision brassing of sleeve-type detail and can be used for application of enduring and antifrictional coverings made of ductile metal on internal cylindrical surfaces of vehicular equipment details. At plating it is implemented outrunning cleaning of treated surface by high-pressure stream of process liquid, which is fed with alternating direction and inclination to work area. Stream is fed from cross-hole, communicating to chamber of internal well, implemented in spent part of chafing roller. It is implemented rolling movement of roller relative to longitudinal axis in the line of opposite direction to sense of power-tooling unit rotation, creating firm precision contact between spent part of chaffing roller and detail surface which is wet by layer of process liquid. Simultaneously it is implemented strengthening treatment by means of superficial-plastic straining of treated surface material of detail by strain hardening depth 70-80 mcm.

EFFECT: providing of effective detail brassing.
