The research provides a valuable contribution to the development of advanced aluminium-based materials for applications where corrosion resistance is critical.
However, future work should consider optimizing cold working parameters, evaluating long-term immersion behaviour, and employing advanced characterization techniques such as XPS or TEM to fully elucidate the mechanisms of oxide film formation and stability.
Moreover, advanced characterization tools such as X-ray Photoelectron Spectroscopy (XPS), Transmission Electron Microscopy (TEM), and X-ray Diffraction (XRD) should be employed in future work to analyze the structure, composition, and crystallinity of the passive films formed on the composite surfaces.

Introduction In recent years, there have been increasing interests in developing bulk metallic glasses (BMGs) with great glass-forming ability (GFA) owing to the unique combination of properties, different from that of conventional materials and the potential engineering applications [1-9].
However, the engineering commercialization of these BMGs as structural materials is hindered by their limited GFA, low thermal stability and unsatisfactory manufacturability [9].
