    Research of wear resistance of bronze bushings during plastic vibration deformation
    (Eastern-European Journal of Enterprise Technologies, 2017-04) Kelemesh, A. O. ; Gorbenko, O. V. ; Dudnikov, A. A.; Dudnikov, I. A.; Келемеш, Антон Олександрович; Горбенко, Олександр Вікторович; Дудніков, Анатолій Андрійович; Дудніков, Ігор Анатолійович
    Optimum design parameters of the tool for vibration deformation of bronze bushings: the punch angle β=9°; the height of the punch gauge part – 4-5 mm are obtained. For treatment of parts, the vibration amplitude of 1.0 mm, the machining allowance of 0.4 mm and the plastic deformation force of 217 N/m2 should be used. The analysis of the microstructure improvement of the parts treated by vibration deformation is presented. Under deformation, more fine grains are formed and favorable conditions for dislocation generation are created, which promotes an increase in the radial deformation rate. The obtained process parameters of vibration deformation of bronze bushings allow reconditioning of worn-out surfaces. They can also be used for treatment of new parts, thus increasing the wear resistance of operating surfaces by 1.2 times. The research results can be useful in the development and improvement of the processes of reconditioning “bushing” type parts.
