Research on corrosion resistance of Al-Fe-Co-Cr-Ni-Cu high-entropy alloy coating by electron beam evaporation plating

NIU Xue-lian;WANG Li-jiu;SUN Dan;DONG Jing-liang;LI Chang-ming;Institute of Building Materials,Faculty of Infrastructure Engineering,Dalian University of Technology;  
High-entropy alloy coatings of AlxFeCoCrNiCu(x=0.25,0.50,1.00)were prepared on steel bar using the electron beam evaporation plating technology,and the effects of different Al contents on corrosion resistance of the coatings were discussed.The phase,microstructure and chemical composition of the prepared coatings were observed with XRD,AFM and EPMA.The experimental results show that the alloy coating surface prepared on smooth base is smooth and with well-distributed thickness,the produced membranous film is dense,and the structure of the prepared high-entropy alloy coating is gradually changed from a single FCC phase to a mixture phase of FCC and BCC with the increase of Al content.The polarization curves show that high-entropy alloy coating has better corrosion resistance than 304stainless steel in 0.5mol/L H2 SO4 solution and 1mol/L NaCl solution,meanwhile Al0.5 FeCoCrNiCu high-entropy alloy coating has the best comprehensive corrosion resistance and pit-corrosion resistance.
