ANGGRAINI, L. et al. Stainless 37 Steel Corrosion Inhibition in a Hydrochloric Acid Solution with Senggani (Melastoma Candidum D. Don) Leaf Extract. Port. Electrochim. Acta [online]. 2023, vol.41, n.3, pp.199-210. Epub 30-Jun-2023. ISSN 0872-1904. https://doi.org/10.4152/pea.2023410302.
SLE (Melastoma candidum D. Don) was tested as an inhibitor of St-37 S corrosion in a HCl solution, using WL, PDP and SEM analysis methods. CR has decreased with SLE addition, according to the WL method. The highest IE(%) was 67%, with 0.8% SLE addition. Rise in T had a decreasing effect on IE(%). PDP showed that the extract was a mixed inhibitor. SEM analysis showed changes in the St-37 S surface immersed in HCl, without and with the inhibitor. SLE adsorption onto the steel surface obeyed Langmuir’s isotherm.
