The paper studied the electrochemical behaviour of FeAl-coatings with different aluminium contents applied by magnetron deposition in various aggressive environments. The coatings were deposited using a modernized VU-1B vacuum installation with two injection targets of iron and aluminium. The coatings were applied to stainless steel 08Kh18N10Т with a thickness of 3 μm. The produced coatings predominantly consist of the FeAl intermetallic phase. The electrochemical behaviour of the coatings was studied in a potentiodynamic mode with 3 % sodium chloride and 10 % sulfate acid at a temperature of 18…20 °C. The corrosion current of magnetron FeAl-coatings is an order of magnitude higher in sodium chloride solution than in sulfuric acid, indicating better corrosion resistance in the latter. It has been shown that the coatings containing 55 at. % aluminium (Fe55Al) exhibit higher corrosion resistance compared to Fe40Al coatings and even surpass that of 12Kh18N10Т stainless steel. The improved resistance of Fe55Al coatings is attributed to the presence of a single FeAl intermetallic phase and the absence of the α-Fe phase, the presence of which in Fe40Al coatings corresponds to increased corrosion processes. The obtained results demonstrate the suitability of Fe55Al magnetron coatings as protective layers for components operating in aggressive environments. 14 Ref., 2 Tabl., 2 Fig.
