Atmospheric corrosion of metals arising from exposure to water vapor is a pervasive problem across wide range practical scenarios, including nuclear material storage and historical artifact conservation. Frequently, it hypothesized that this phenomenon becomes an issue once the number monolayers growing atop substrate sufficient facilitate chemistry, but supporting evidence remains scarce. We apply both near ambient pressure X-ray photoelectron spectroscopy vibrational sum frequency further elucidate interaction with zinc, common engineering for protection applications. Data acquired as function relative humidity indicate sorption much more complex than expected, involving micropore filling capillary condensation in adventitious carbon layer covering zinc surface. These results suggest current mechanistic models atmospheric corrosion, well other interfacial phenomena occurring humid environments, require extensive revision should embrace explicit consideration role surface contamination.
