Claims (1)

Способ восстановления изношенных деталей железнодорожной техники методом плазменно-порошковой наплавки, включающий демонтаж изношенных первичных деталей из соответствующих узлов железнодорожной техники, входную дефектоскопию подповерхностной толщи поступающих деталей, отсортировывание дефектовыправимых реконструкциепригодных единиц, внешнеповерхностную ревизию их рабочих элементов и переработку первичных деталей во вторичные эксплуатационные детали, предполагающее базирование каждой из первичных деталей на фиксационном приспособлении токарного станка, освобождение сохраненного подложечного слоя тела детали от коррозированного слоя, преднаплавочную подготовку подложечного слоя дробеструйной обработкой, акселерирование имеющей место межоперационной паузы, электропотенцирование подготовленного подложечного слоя для чернового плазмопрогрева и рабочего плазмонапыления металлонаплавки, а также финишную шлифовочно-абразивную отделку поверхности металлонаплавки и отвод полученных вторичных деталей на выходной контроль и маркировку, отличающийся тем, что финишную шлифовочно-абразивную отделку металлонаплавки производят как электрофорсированную, для чего осуществляемое электропотенцирование продолжают вести как перенесенное с подложечного слоя на отделываемую металлонаплавку, и его обеспечивают подачей на восстанавливаемую деталь потенциала напряжением 0,1 - 12,0 В.A method for restoring worn-out parts of railway equipment using a plasma-powder surfacing method, including dismantling worn-out primary parts from the corresponding nodes of railway equipment, input flaw detection of the subsurface thickness of incoming parts, sorting out defects of correctable reconstruction of suitable units, external surface inspection of their working elements, and processing of primary parts into secondary operational parts, which involves basing of each of the primary parts on the fixation the turning of the lathe, the release of the stored substrate layer of the body of the part from the corroded layer, pre-melting preparation of the substrate layer by shot-blasting, the acceleration of the interoperational pause, electropotentization of the prepared substrate layer for rough plasma heating and working plasma spraying of metal melting, as well as for finishing grinding and surfacing received secondary parts for output control and marking, characterized in then finish semolina-abrasive finish metallonaplavki produce both elektroforsirovannuyu, which carried elektropotentsirovanie continue to lead both transferred from the pit layer metallonaplavku trim, and its supply to the detail of the restored building voltage 0.1 - 12.0 V.
