This research studied the behavior of NiCrFeNbMoTiAl metallic coating under corrosive attack by molten salts 80% Na2SO4 – 20%V2O5 and 80%K2SO4 – 20%V2O5 deposited by non-transfer arc plasma-assisted thermal spraying (APS) at a temperature of 700ºC. Corrosion rate were determined by means of linear polarization resistance (LPR), electrochemical techniques, and electrochemical impedance spectroscopy (EIS). The results obtained showed a high severity of attack from the 80%Na2SO4 – 20%V2O5 mixture. Nyquist plots show a trend that the load transfer mechanism was the predominant factor in the process activation.
