METHOD FOR MAKING MUTUALLY JOINED PORTIONS OF PART Russian patent published in 2002 - IPC

Abstract RU 2189293 C2

FIELD: powder metallurgy. SUBSTANCE: method comprises steps of pressing iron-base powder in form with one die having cavity for molding non-sintered part made as monolithic one; subjecting non-sintered part to mechanical working; cleaving with fracture non-sintered part at least by two portions along surface designed for parting; sintering portions of part; joining then to single part along parting surfaces. EFFECT: possibility for making mutually joined portions of part without microshifts and plastic deformation on surface of fracture. 10 cl, 1 tbl
