Abstract
Microstructure and corrosion properties evaluation of MnCrFeCoNi high entropy alloys (HEA) composite coatings containing five different graphene oxide (GO) amounts was conducted. The HEA coatings were electrodeposited over mild steel substrate. The corrosion resistance properties of the HEA and HEA-GO composite coatings determined using potentiodynamic polarization and electrochemical impedance spectroscopy tests conducted in 3.5% NaCl solution revealed that with the addition of GO the corrosion resistance of the coating increased. Detailed microstructural characterization using the electron microscopy technique showed that GO enhanced the amount of Mn and Cr in the coatings leading to higher corrosion resistance.
