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.

两种新颖的Fe ₇₈ Co ₉ Cr ₁₀ Mo ₂ Al ₁和Fe ₄₉ Co ₄₉ V ₂（at。％）金属-金属玻璃态合金是在人造海水中于27°C和pH值在7.5-8.5范围内进行研究的。两种合金的腐蚀行为均通过电化学技术（例如电化学阻抗谱（EIS）和循环极化（CP）测量）以及物理技术（例如X射线光电子能谱（XPS），扫描电子显微镜（SEM）和原子力显微镜（AFM）。观察到两种合金的电阻与pH值升高之间的良好一致性。VX50合金的高腐蚀速率与合金表面无钝化行为有关。由于诸如Cr的合金元素，VX9合金表现出低的腐蚀电流密度和低的腐蚀速率，这使得能够形成保护膜。
