In the atmospheric corrosion of copper, nickel, and iron, adsorption of water affects corrosion rates. Knowledge of water adsorption and metal oxy hydroxide formation is important in understanding the atmospheric corrosion process. Gold provides a model system because it retains its surface characteristics throughout adsorption experiments. The quartz-crystal microbalance (QCM) technique was used to measure the mass change of gold at 0% to 100% relative humidities (RH) and from 7°C to 90°C under nitrogen (N2) environments. Shapes of the Isotherms suggested capillary condensation and filling of pores, in addition to physical adsorption, occur on gold and are more significant at higher temperatures. Adsorption isotherms observed were of Type III and Type IV according to the Brunauer-Emmett-Teller (BET) classification.
