The inhibition effects of methionine on mild steel in acidic media

Corrosion Inhibition of Mild Steel in Acidic Solution by Apricot Gum as a Green Inhibitor

The inhibitive effect of apricot gum AG on mild steel in 0.5 M phosphoric acid solution was investigated by potentiodynamic polarization, electrochemical impedance spectroscopy EIS, linear polarization resistance and electrochemical noise EN techniques. The inhibition efficiency increased with increasing AG concentration up to a certain value and decreased with increasing temperature. Polarizat...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

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

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 ...
