Abstract
Способ термоциклической диффузии металлических порошков для восстановления изношенных поверхностей бронзовых втулок скольжения, характеризующийся тем, что включает в себя цикловой нагрев втулки и порошка на основе бронзы до температуры расплава порошка и диффузии его в металл втулки, временной выдержки при температуре начального диффузионного процесса, затем охлаждение детали до температуры фазового спекания порошка, выдержка в данном интервале температуры, вторичный нагрев до температуры начального расплава порошка с временем выдержки для приращения восстанавливаемого диффузионного слоя, затем охлаждение до номинальной температуры.A method for thermocyclic diffusion of metal powders to restore worn surfaces of bronze slide bushings, characterized in that it includes cyclic heating of the bronze-based sleeve and powder to the temperature of the powder melt and diffusion into the sleeve metal, temporary exposure at the temperature of the initial diffusion process, then cooling the part to the phase sintering temperature of the powder, holding in this temperature range, secondary heating to the temperature of the initial powder melt with time erzhki to increment recovered diffusion layer, then cooling to a nominal temperature.
