A microclimate model was developed to create a virtual NSS test for evaluating the response of coated metal surface to controlled environments. The presented model is able to interact with other corrosion models and utilise empirical data to predict pit growth rate. Inhibition efficiency of coating systems can be assessed and compared under different microclimates. This work demonstrates an effective approach for simulating environmental conditions for pit corrosion evaluation and inhibitor assessment.
The model uses a dynamic process to simulate salt fog droplet formation, subsequent coalescence, and movement on a coated surface, to determine wet-dry cycles on realistic test samples. While the presented model is formulated to comply with standardised NSS tests, e. ASTM B117, the developed method can be tuned to simulate a variety of common cyclic environmental testing conditions, and has wide applicability for the virtual assessment of functional coatings.
