Corrosion Inhibition by Tithonia diversifolia (Hemsl) A. Gray leaves extract for 304 SS in hydrochloric acid solution

[摘要] The inhibition effect of Tithonia diversifolia (Hemsl) A. Gray leaves extract on the corrosion phenomena of 304 SS in 1 M HCl has been studied by polarization potentiodynamic. The powder of T. diversifolia was extracted by demineralized water which was cultivated in East Java, Indonesia. The extract was characterized by FTIR spectrophotometer. The presence of T. diversifolia can inhibit the corrosion rate of 304 SS. The efficiency inhibition value of 2 g/L T. diversifolia leaves extract reached up to 77.27% at room temperature.
