Abstract
The impact of duration of high-energy processing of the mixture of 60.8Fe + 39.2TiAl powders (wt. %) on structure, phase composition and mechanical characteristics of plasma intermetallic (Fe,Ti)₃Al coatings was studied. As powders, for plasma spraying powders of (Fe,Ti)3Al intermetallic were used, which were produced by the method of mechanochemical synthesis (MChS) in a high-energy mill for 3 and 5 h. As a result of plasma spraying, coatings with a nanocrystalline structure with the size of crystallites of 60 and 45 nm are formed, respectively. It was shown that during spraying of MChS-powder, produced during 5 h, thin-lamellar coatings with a maximum thickness of lamellae of 23 μm are formed, whereas in the case of spraying of MChS-powder produced within 3 h, the thickness of lamellae reaches 42 μm. At the same time, in the case of spraying MChS powder, produced within 5 h, more dense coatings are formed, the porosity of which is reduced by 2.3 % compared to the coating from the MChS-powder, produced within 3 h. It was established that mechanical characteristics (hardness and module of elasticity) of the plasma coating were increased when using a powder produced by processing within 5 h. This allows predicting higher wear resistance of these coatings, operating in the conditions of wear unlike the case of spraying MChS-powder, produced within 3 h. 15 Ref., 3 Tabl., 5 Fig.
