Inhibitive Effect of<i> Costus afer</i> Extracts on Mild Steel Corrosion in Acidic Medium

Corrosive Inhibitive Effect of Pyrazole Compounds towards the Corrosion of Mild Steel in Acidic Medium

The inhibitive effect of compound (1-acetyl-4, 5-dihydro-5-Bromophenyl-3-(thiophen-2yl) pyrazoles) on mild steel in 1M H2SO4 and 1M HCl was investigated by weight loss, Potentiodynamic polarization and electro chemical impidence studies. The synthesized compound of 1-acetyl-4, 5-dihydro-5-Bromophenyl-3-(thiophen-2yl) pyrazoles was characterized by FTIR, H NMR, C NMR and mass. The purity of the ...

Corrosion inhibitory action of some plant extracts on the corrosion of mild steel in acidic media

CORROSION INHIBITIVE PROPERTIES OF EXTRACT OF JATROPHA CURCAS LEAVES ON MILD STEEL IN HYDROCHLORIC ACID ENVIRONMENT

Jatropha curcas leaves extract was tested as a green corrosion inhibitor for mild steel in aqueous hydrochloric acid solution using gravimetric and thermometric techniques. The results reveal that the inhibition efficiency vary with concentration of the leaf extract and the time of immersion. Maximum inhibition efficiency was found to be 95.92% in 2M HCl with 0.5 g/l concentration of the extrac...

Synergistic Effect of Potassium Iodide on Corrosion Inhibition of Mild Steel in HCl Medium by Extracts of Nypa Fruticans’ Wurmb

The effect of Nypa fruticans’ wurmb extract and the mixture of various concentration of KI and Nypa fruticans’ wurmb extract on corrosion of mild steel in 0.1M and 0.5M HCl have been investigated using weight loss methods. The study revealed that mild steel is more efficiently inhibited by Nypa fruticans’ wurmb in the presence of KI than pure extract of Nypa fruticans’ wurmb. The inhibition eff...

Effect of piperidones on hydrogen permeation and corrosion inhibition of mild steel in acidic solutions

The influence of 3-methyl-2,6-diphenyl piperidin-4-one (MDPO) and 2phenyl decahydroquinoline-4-one (PDQO) synthesised in the laboratory on hydrogen permeation and corrosion inhibition of mild steel in 1N H2SO4 has been studied using weight loss and various electrochemical AC and DC corrosion-monitoring techniques. Both the compounds inhibit the corrosion of mild steel in H2SO4. Potentiodynamic ...
