Synthetically Modified Tara and Oak Gall Nut Tannin‐Based Corrosion Inhibitors for Combating the Corrosive Influence of Acidithiobacillus thiooxidans on Mild Steel

International Journal of Corrosion, Volume 2024, Issue 1, 2024.
Natural tara and oak gall nut tannins, which lack corrosion inhibitive properties, were modified using gum arabic and tested against microbial corrosion induced by Acidithiobacillus thiooxidans under isothermal condition (28°C). Mild steel coated with the modified tannins was exposed to the causative under aerobic and anaerobic conditions. Based on the

Characteristic investigation of stress-hydrogen coupling hydrogen diffusion of X80 steel based on finite element simulation [PDF]

MATEC Web of Conferences
Since hydrogen atoms are enriched in the corrosion defect regions of steel pipelines under stress-induced effects when transporting gaseous hydrogen, this leads to the hydrogen embrittlement (HE) phenomenon.
