Titanium resists corrosion not because of its bulk chemistry but because of an invisible oxide film \u2014 just 2\u20136 nanometers thick \u2014 that forms on its surface within microseconds of oxygen exposure. This film, composed primarily of titanium dioxide (TiO\u2082), acts as a dense ionic barrier that physically isolates the underlying metal from corrosive environments.
