dc.description.abstractТимол досліджено як новий леткий інгібітор атмосферної корозії сталі. Для оцінки складу та характеристики сформованих захисних шарів використовували гравіметричні та електрохімічні дослідження, доповнені спектральними FT-IR та мікроскопічними методами аналізу SEM. Плівка, утворена на поверхні сталі з парогазової фази тимолу, забезпечує ефект післядії на рівні 90% за періодичної конденсації вологи впродовж 504 годин. Для оцінки адсорбційної здатності тимолу проведені квантово-хімічні розрахунки енергетичних параметрів молекули тимолу.
dc.description.abstractThe inhibition effect of thymol during the early stage of steel corrosion under adsorbed thin electrolyte layers was investigated. Its vapor corrosion inhibition property was evaluated under simulated operational conditions. Electrochemical techniques complemented by FTIR and SEM surface analyses were used to evaluate the composition and characteristics of the layers. The results indicate that thymol can form a protective film on the metal surface, which protects the metal against further corrosion. Quantum chemical calculations studies were also performed to support weight loss and electrochemical experimental observations.
