Résumé : |
Quantitative information on the water layer at the coating/substrate interface is crucial for understanding and preventing the failure of organic coating systems. A method, based on a two-layered model derived rigorously from internal reflection theory, was developed for determining the amount and thickness of water at the organic coating/substrate interface. The method gives new insight into the processes by which water degrades the coating/substrate bonds. The method requires application of a transparent or opaque organic coating of sufficient thickness on an internal reflection element (IRE), which is used as the substrate. A water chamber is attached to the coated specimen (...) |
