چکیده انگلیسی
High-entropy alloys (HEAs) are a newly developed family of multi-component alloys. The potentiodynamic polarization and electrochemical impedance spectroscopy of the AlxCrFe1.5MnNi0.5 alloys, obtained in H2SO4 and NaCl solutions, clearly revealed that the corrosion resistance increases as the concentration of aluminium decreases. The AlxCrFe1.5MnNi0.5 alloys exhibited a wide passive region, which extended >1000 mV in acidic environments. The Nyquist plots of the Al-containing alloys had two capacitive loops, which represented the electrical double layer and the adsorptive layer. SEM micrographs revealed that the general and pitting corrosion susceptibility of the HEAs increased as the amount of aluminium in the alloy increased.
