Abstract

Iron aluminide powders obtained by the method of plasma-arc spraying of a flux-cored conductive wire with a steel shell and an aluminium filler were investigated. The experi­ments were carried out in an argon environment on the “PLAZAR-50-PL-W” installation. It was established that at all operation modes of the plasma torch, the sputtered particles are mostly spherical in shape. The number of particles of non-spherical shape is 7–12% in powders of the –315+200 mm fraction and in smaller fractions it is equal to 4–5%. The main phases of the obtained materials are Fe₃Al and FeAl iron aluminides in various ratios. In all powder fractions the amount of the metal component is greater than of the oxide component. The number of oxides increases with a decrease in the powder fraction and a decrease in the plasma torch current. Under spraying at a current of 220 and 270 A in the powder fraction –200 + 100 mm, a larger amount of aluminides 83.88 and 86.30 and the lowest content of oxides up to 10–18% was recorded. In smaller powder fractions the content of aluminides is 70.38–75.68, and the amount of the oxide component increases to 29.62 wt%. The microhardness of metal particles is 3.07–4.59 GPa. Oxide particles consist mainly of Fe₃O₄ and Fe₂O₃ iron oxides and have a higher microhardness of 5.32–8.15 GPa under all spraying modes. The obtained powders can be recommended in 3D production for the direct energy deposition method, which includes laser deposition processes (DMD – Direct Metal Deposition). These materials can be used in the pro­duction of precise workpieces with a minimum allowance for mechanical processing using compaction methods in granular metallurgy – hot isostatic pressing (HIP).
