The accumulation of adventitious carbon on Al and Au–Al alloy surfaces has been studied using XPS across a wide range of water vapour and air exposures. Carbon growth undergoes several discrete changes with the increase of exposure dose. X‐ray irradiation effects on carbon growth were also investigated. Under x‐ray irradiation Au–Al surfaces show a faster carbon growth than pure Al and Au metal surfaces. A fivefold increase of carbon contamination rate on an Au‐rich Au–Al alloy (Au/Al = 5.0) surface has been observed. Copyright © 2002 John Wiley & Sons, Ltd.
