Microstructure and corrosion resistance of AlCrFeCuCo high entropy alloy
چکیده انگلیسی

The AlCrFeCuCo high-entropy alloys were prepared by the laser cladding method. The microstructure and corrosion resistance property of AlCrFeCuCo high-entropy alloy were researched by scanning electron microscopy, X-ray diffraction and electrochemical workstation. The results show that, under the rapid solidification small microstructure gained, the morphology of AlCrFeCuCo high entropy alloy is simple, the phase mainly compose of FCC and BCC; elements segregated in the alloys; the alloy shows excellent corrosion resistance, along with the increase of the scanning speed, alloy corrosion resistance performance shows a enhancement in the first and then weakened trend. The corrosion resistance performance of AlCrFeCuCo high-entropy alloys in 1 mol/L NaCl solution is better than in 0.5 mol/L H2SO4 solution.


► We use a new method (laser cladding) to prepare high-entropy alloy.
► We gained small microstructure under rapid solidification condition.
► We studied corrosion resistance of AlCrFeCuCo high-entropy alloy in two different liquids.
