Two novel Fe78Co9Cr10Mo2Al1 and Fe49Co49V2 (at.%) metal-metal glassy alloys were studied in artificial seawater at 27 °C with pH values in the 7.5-8.5 range. The corrosion behavior of both alloys was investigated by using electrochemical techniques such as electrochemical impedance spectroscopy (EIS) and cyclic polarization (CP) measurements as well as physical techniques such as x-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and atomic force microscopy (AFM). Good agreement between the resistance of both alloys with rising pH values was observed. The high corrosion rate for the VX50 alloy is related to the absence of passivation behavior on the alloy surface. The VX9 alloy shows a low corrosion current density and a low corrosion rate due to the alloying element such as Cr, which enables the formation of a protective film.
