Abstract In-situ infrared reflection absorption spectroscopy (IRAS) was a very powerful tool for studies of corrosion processes of the confi ned metals in the atmosphere.In this paper,an in-situ IRAS cell was set up and t he corrosion process of zinc and water evaporation in the drying process on the confined zinc surface exposure under periodic wet dry conditions was studied by in-situ IRAS.The water thickness on the confined surface of zinc could be calcul ated according to the optical index.The corrosion product formed in the initial stage of the confined zinc in the purified air with the relative humidity of 50% mainly was ZnO,The amount of corrosion product on the confined zinc surface inc reased linearly with day,the corrosion rate decreased with time during each dryi ng process.
