The use of varied quantities of orphenadrine to protect stainless steel against corrosion in an acidic media at 298 K has been investigated. It was observed that when the drug's concentration is increased, the drug's speed of corrosion lowers. The data of inhibition efficiency (percent IE) in the presence of orphenadrine drug and corrosion resistance showed that the highest protection efficiency was achieved with the best concentration, and that the corrosion rate decreased with increasing orphenadrine drug concentrations, making it a good inhibitor for stainless steel in an acidic environment. The theoretical investigation proved the efficiency of the drug for inhibition, as the drug is absorbed on the surface of the stainless steel by the active groups in the drug, using the hyperchem-8.07 software to compute the molecular orbital energies.

“…The surface morphology analysis confirmed the film formation by inhibitor molecules on mild steel surface. Chakravarthy and Mohana 20 have reported the synthesis of some isonicotinic acid hydrazides namely, isonicotinic acid (1H-indol-3-yl-methylene)hydrazide (HD 25 ) and isonicotinic acid (1H-pyrrol-2-yl-methylene)hydrazide (HD 26 ), and study of their inhibitive characteristics in 0.5 M HCl against corrosion of mild steel. Polarization results indicated the mixed type behaviour of compounds, HD 25 and HD 26 .…”

This paper gives an overview of the application of hydrazide derivatives in acid media as corrosion inhibitors of mild steel. In chemical and petrochemical industries, mild steel is the major constructional material widely used. Acid solutions have been commonly used in these industries as pickling agents to remove rust or any scale from the mild steel surface. The excessive dissolution of mild steel in such aggressive medium can be best controlled by addition of suitable organic inhibitors. Hydrazide derivatives are widely used in such applications as mild steel corrosion inhibitors. The various factors which influence the corrosion inhibition efficiency of different hydrazide derivatives have been discussed. The information provided is useful for various industries where corrosion inhibitors are needed to protect mild steel structures which are being exposed to hydrochloric or sulphuric acid solutions.

“…The mechanism of this protection depends on the metal and inhibitor under consideration. In most cases, however, it is due to the adsorption of these compounds onto the surface of metals which can reduce the extent of corrosion through thermodynamics or kinetics phenomena [3][4][5][6]. The effectiveness of any corrosion inhibitor is dependent on the type of metal and properties of the corrosive environment [7][8][9][10][11].…”

The inhibition effect of new synthesized amphoteric and di‐cationic surfactants, namely: 4‐((((1‐dodecylpyridin‐1‐ium bromide)‐4‐yl)methylene)amino)benzoate sodium (I) and 1‐dodecyl‐4‐(((1‐dodecylpyridin‐1‐ium‐4‐yl)imino)methyl)pyridin‐1‐ium bromide (II), respectively, on the corrosion of carbon steel in 1 M HCl have been investigated using electrochemical impedance spectroscopy, Tafel polarization and weight loss measurements. The inhibition efficiencies obtained from all methods employed are in good agreement with each other. Tafel polarization studies showed that the surfactants are mixed type inhibitors. The adsorption of two compounds onto the surface of carbon steel in 1 M HCl obeys the Langmuir isotherm. Adsorption thermodynamic parameters reveal that the adsorption of inhibitors is a mixture of physical and chemical adsorption.
