Abstract
Structure, composition and microhardness of detonation coatings were examined. They were received using Fe₂Al, FeAl and Fe₂Al₅ intermetallic powders, produced by mechanical alloying (MA) method, and mixtures of Fe and Al powders of equivalent compositions. An effect of «oxygen–combustible gas» relationship in the detonation mixture on oxidation process of material being sprayed was determined. The results of determination of phase composition of the coatings, deposited using different powders, show that in case of application of mechanical mixtures a layer mainly consists of the particles of Fe and al initial mixture. A structure of coatings of MA Fe–Al-powders contains mixture of heating and oxidation products of these powders. Microhardness of the coatings varies from 4580 to 5710 MPa depending on composition. 21 Ref., 3 Tables, 8 Figures.
