In this work, the essential oil of black pine (Pinus nigra J. F. Arnold) was used for first time as a natural, ecological, and sustainable corrosion inhibitor acid cleaning carbon steel. The extracted by hydrodistillation using Clevenger-type apparatus, analyzed gas chromatography–flame–ionization detection (GC–FID) chromatography–mass spectrometry (GC–MS). most abundant components in were α-pinene, germacrene D, (E)-cariophyllene, β-pinene. inhibition efficiency determined electrochemical methods (electrochemical impedance spectroscopy potentiodynamic polarization measurements). results showed that inhibitory increases with time, reaching highest values after 4 h immersion all concentrations. It also shown is mixed-type inhibitor. contact angle measurements confirmed oil, new environmentally safe inhibitor, able to protect steel from 1 M HCl solution.

The present study investigates the inhibition potential of Tinospora cordifolia extract in combination with different methanol solvents on corrosion carbon steel artificial seawater environments. Potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) methods were utilized to evaluate this inhibitor. measurement data show a positive correlation among efficiency (%IE), inhibitor concentration, temperature, time. However, above 320 K, has slight decline, as well when exposure duration extends beyond 30 minutes. highest observed was 85.94%, achieved by incorporating 300 mgL−1 T.
