Apstrakt:
In this paper, the inhibitory effect of thyme extract on the corrosion of two types of steel in 3% NaCl solution was investigated. Steel samples were immersed in 3% NaCl solution without inhibitor and solutions with 0.5, 1.0 and 1.5 g/L inhibitor (thyme extract), and the exposure times to the corrosive environment were 2, 4, 6, 8, 24, 48 and 168 hours. MINITAB 21 software was used to optimize and process the experimentally obtained results, and the analyzed parameters were corrosion rate (Km-), corrosion depth index (π) and inhibitor efficiency (z). It was found that the use of inhibitors significantly reduces the corrosion rate and increases the protection efficiency, and the highest efficiency (z>85%) is at an inhibitor concentration of 1.5 g/L after 48 and 168 hours. Steel 2 showed higher resistance in the absence of inhibitors, while the addition of inhibitors significantly reduced the corrosion rate of both steels.
