| Sumari: | Title screen The paper considers the influence of nanostructured powder-modifiers on the nature of the transfer of electrode metal and the process of structure formation of the deposited metal during surfacing with a consumable electrode in argon. It was found that the more short circuits and less energy is required to ionize the gas mixture in the arc plasma, the more stable the surfacing process. From this position, the most stable is the surfacing process with the use of AlO(OH) nanopowder (10 short circuits per sec.). It was revealed that the sizes of metal droplets change with the introduction of nanopowder, acquiring a more elongated shape, which contributes to a better transition of the metal into the weld pool, thereby reducing spatter. It has been established that when the deposited metal is modified with ultra-dispersed powders, the size of the dendrites decreases in comparison with the deposition without modifiers. A more equilibrium structure in terms of the size of the dendrite is achieved using ultrafine AlO(OH) powder. |
