passivatiefilm
A passivation film, also known as a passive film, is a thin layer of oxide that forms on the surface of certain metals, particularly stainless steel and aluminum, when exposed to an oxidizing environment. This film is crucial for the corrosion resistance of these metals. The formation of a passivation film is typically facilitated by the presence of oxygen or other oxidizing agents in the environment. The film acts as a protective barrier, preventing further oxidation and corrosion of the underlying metal.
The passivation process can be either natural or induced. Natural passivation occurs spontaneously when the metal
The thickness and composition of the passivation film can vary depending on the metal, the environment, and
The integrity of the passivation film is essential for maintaining the corrosion resistance of the metal. Any
