ODUNLAMI, Olayemi et al. Citrus Paradisi Organic Inhibitor Effect on Ti Steel Corrosion in Acidic Solutions. Port. Electrochim. Acta [online]. 2024, vol.42, n.2, pp.115-122.  Epub Jan 31, 2024. ISSN 0872-1904.  https://doi.org/10.4152/pea.2024420203.

The word corrosion has been a major issue in the industry, especially in industrial infrastructures, such as steel materials, causing great losses in revenues and environmental pollution. This research goal was to contribute to solving the aforementioned issues. CP as CI, on TS samples in 0.5 M HCl and 0.25 M H2SO4 media, was studied via electrochemical, FTIR and OM techniques. All the results proved the presence of active components in CP, which mitigated TS samples corrosion in the corrosive media. CR reduced greatly for all the TS samples, as CP IE(%) increased. Also, OCP showed that CP operated with mixed adsorption mechanisms. FTIR analysis revealed the numerous functional groups that enabled CP IE(%), by retarding TS samples corrosion. OM images showed the corrosion damage on TS samples without CP, and the film coverage on the alloy, after the inhibitor addition. This confirms CP excellent adsorption onto TS samples.

Keywords : active components; CI; CR, functional groups; FTIR; OM.
