The work is dedicated to investigation of process of formation of Fe-Al coating with regulated composition on substrates of 08Kh18N10T steel at mutual magnetron sputtering of composite Al + Fe target with heated above the Curie point (768 °C) insert of St.3 and aluminum target. Application of a system of cyclic substrate movement in the active zones of magnetron operation allowed forming a nanolayer structure of coatings with Al — 1.3–1.9 and Fe — 1.6 nm nanolayer thickness. The coatings were investigated using Auger spectrometry, X-ray diffraction and microindentation. It is determined that 3 mm FeAl-coatings containing 39.6 and 54.6 at.% of Al are an ordered B2 — FeAl phase consisting of 0.135–0.173 and 0.293–0.335 mm size grains, formed from nanocrystallites of 7 and 22 nm, respectively. 17 Ref., 4 Tables, 6 Figures.
