“…In recent times, the entire attention is focused on the natural products and plant materials as effective inhibitors, since they met the requirements of an eco-friendly cost-effective inhibitor. Literature provides the details of a wide spectrum of green strategies adopted for the corrosion inhibition of various metals and alloys in different environments [4][5][6][7].…”

Aqueous leaves extract of Clerodendrum infortunatum (CIW) was used as inhibitor for mild steel corrosion in 0.5 N HCl. Inhibition efficiency decreases with temperature. The presence of 1heptatriacotanol, the diterpene alcohols like phytol and 3, 7, 11, 15 tetramethyl-2-hexadecen-1-ol are identified as major constituents through GC-MS analysis of CIW. The electronic properties and inhibition efficiency of these compounds were evaluated using DFT and material studio software. The donor-acceptor type interactions resulting from the migration of lone pair of electrons of the 'O' atom of these molecules to the vacant 'd' orbital of the metal is evident from these calculations. The reduction in the double-layer capacitance with the incremental addition of CIW is noticed. CIW offers mixed inhibition with anodic predominance. CIW forms a multimolecular layer on the metal surface obeying the Temkin isotherm model. Surface perturbations were followed qualitatively by SEM, stereomicroscope and XPS.

“…The impact of corrosion on mild steel is especially exacerbating in marine, petrochemical and mining environments considering [20][21][22][23][24][25]. On a national level corrosion cost is about 1-5% of a nation's Gross Domestic Product [26]. The corrosion problem for mild steel can be minimized when used in environments with effective corrosion inhibitors [27].…”

Analysis and description of inhibition efficiency results for tea tree and grapefruit essential oil extracts (TTGP) on mild steel (MS) and alloy steel 3310 (AS3310) in 0.5 M H2SO4 solution was done. The results show TTGP performed effectively on MS at 2% to 3.5% TTGP concentration with final inhibition values of 71.70%, 79.25%, 83.58% and 92.45% at 240 h of exposure. Inhibition efficiency generally increased with TTGP concentration and exposure time, although inhibition efficiency at 2.5% 3% TTGP concentration decreased with exposure time. Effective TTGP inhibition performance on AS3310 occurred at 3% and 3.5% TTGP concentration only with final values of 72.50% and 73.25%. Inhibition efficiency of TTGP on AS3310 varied non-proportionately with its concentration. With respect to exposure time, inhibition efficiency of TTGP on AS3310 at all concentrations decreased. Results from ANOVA analysis shows TTGP concentration significantly influenced the performance output of TTGP extract with statistically significant factor of 85.73% and 84.78% (MS and AS3310). The corresponding values for exposure time, though determined to be statistically relevant is overwhelmingly far below the influence of exposure time at values of 4.63 and 14.27. Standard deviation data shows inhibition efficiency of TTGP on MS varied minimally from mean values at all concentrations (excluding 1.5% and 2% TTGP concentration). The corresponding values for TTGP on AS3310 were also generally low at all concentrations signifying stable inhibition performance. Data showed 48% and 18% of MS and AS3310 inhibition efficiency results are greater than 80% effective inhibition performance threshold at margins of error of 12.64% and 10%
