Abstract: 
The 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.
