TY - JOUR ID - TI - Milk Thistle Leaves Aqueous Extract as a New Corrosion Inhibitor for Aluminum Alloys in Alkaline Medium AU - Khudhair Abbas Kareem Al-Rudaini * AU - Khulood Abid Saleh Al-Saadie PY - 2021 VL - 62 IS - 2 SP - 363 EP - 372 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - The aqueous extract of milk thistle (Silybum marianum) leaves as a green corrosion inhibitor for AA7051 aluminum alloy in sodium hydroxide solution was investigated at a range of temperatures. Potentiodynamic polarization findings exhibit a mixed–type inhibitor with directly increased inhibition efficiency with the concentration of inhibitor. The adsorption of the inhibitor on aluminum alloy obeys Langmuir isotherm and the kinetic as well as thermodynamic parameters were measured and discussed.
