AlCrNi(Co)Fe high entropy alloys with or without minor alloying additions, produced by either arc melting or by ingot metallurgy, were tested for corrosion resistance in different chemical environments comprising: sodium chloride at 3.5 wt.%, artificial sea water and 0.1 M sulfuric acid. The experiments were conducted mostly at room temperature and in some cases also at 50 oC, and in non-deaerated liquid media. Characterization of chemical behavior was based on immersion tests, OCV measurements, potentiodynamic measurements, impedance spectroscopy followed by post-exposure analysis involving visual inspection, SEM, EDS, XRD of the surface and ICP of the solutions being in contact with the samples. Overall behavior of the alloys was influenced by their exact chemical composition, distribution of phases and occurrence of physical defects on the surface.
Investigations were conducted within NADEA project (M-ERA.NET 2017). Financial support from the National Science Centre Poland (UMO-2017/26/Z/ST8/01238) is gratefully acknowledged.
