Abstract
The paper studies the electrochemical behaviour of FeAl-coatings with different aluminium content deposited by magnetron
sputtering in various aggressive environments. The coatings were applied using a modified VU-1B vacuum installation with
two targets of iron and aluminium. The coatings were deposited to stainless steel 08Khl8N10T 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 % sulphuric acid solutions at a temperature of 18–20 °C.
The corrosion current of magnetron FeAl-coatings is by an order of magnitude higher in a 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 12Khl8N10T 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 increasing corrosion processes. The obtained
results demonstrate the suitability of using magnetron-sputtered Fe55Al-coatings as a protective layer for components
operating in aggressive environments.
