Oxide film formation on material surfaces, upon oxygen contact, is critical. While it can protect from further corrosion in some instances, it can also degrade the material over time. Therefore, it's vital to understand early oxide film formation stages for designing corrosion-resistant materials. This study utilized correlative and in situ techniques, specifically transmission electron microscopy (TEM) and atom probe tomography (APT), to examine oxide film's initial formation stages on a high entropy alloy (HEA). By observing the chemical changes and phase transformation from a single to a multi-layer oxide film over time, we garnered valuable insights into the process. This research underscores these techniques' potential in facilitating a deeper comprehension of oxide film formation, aiding in designing durable, corrosion-resistant materials.
