METHOD OF INDUCTION SURFACING Russian patent published in 2014 - IPC B23K13/01 B22D19/00 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used for increasing wear resistance of outer cylindrical surfaces. Proposed method comprises placing the article horizontally, placing two plates in symmetry relative to vertical, plates being made of graphite and spaced there between being equal to width of ply being built-up and height exceeding ply height. Portion of facing material is applied between the plates. Facing material and article surface are processed unless their joint fusion. After processing by inductor and a melt hardening the article is turned through surfacing pitch equal to the sum of applied ply width and plate depth. Then, first plate as seen along turning direction is moved to the place occupied by the second plate. Surfacing material is applied between the plates and processed by inductor. After melt hardening, the article is again turned through the same surfacing pitch to reiterate surfacing cycles unless grooves are formed over its entire surface. Now the built-up surface is turned to required diameter.

EFFECT: optimised process, higher tribotechnical properties.
