Abstract
Способ восстановления шеек коленчатых валов, включающий выполнение подготовительных операций для шеек коленчатого вала: мойку, очистку, обжиг, контроль геометрических параметров и дефектоскопию, отличающийся тем, что восстанавливаемые шейки напыляют металлопокрытием, которое состоит из последовательно наложенных друг на друга двух слоев композиционных материалов: первого слоя порошком ВК-25 толщиной 0,020-0,035 мм и рабочего износостойкого слоя самофлюсующим порошковым материалом, нанесение слоев осуществляют детонационным напылением, затем пригалтельные участки и фаски отверстий маслоканалов закрепляют электроконтактным оплавлением до образования диффузионных связей с основой детали.A method for restoring crankshaft necks, including preparatory operations for crankshaft necks: washing, cleaning, firing, checking geometric parameters and flaw detection, characterized in that the necks being restored are sprayed with a metal coating, which consists of two layers of composite materials successively superimposed on top of each other: the first a layer of VK-25 powder with a thickness of 0.020-0.035 mm and a working wear-resistant layer with self-fluxing powder material, the deposition of layers is carried out by detonation spraying, s Then, the cantilevered sections and chamfers of the openings of the oil channels are fixed by electrical contact fusion until the formation of diffusion bonds with the base of the part.
