“…19 In general, compounds of organic origin are known to have good corrosion inhibition characteristics for mild steel in acidic environments. [20][21][22][23][24][25] From this research work, benzamine as an organic compound can be considered as one of such compounds with very appreciable corrosion inhibition in strong acid like H 2 SO 4 even at low concentrations as obtained in this investigation. Benzamide can also be considered as an environmentally friendly inhibitor among many others that are currently receiving significant research attention in corrosion protection studies.…”

“…However, the presence of halide ions in the solution such as the chloride may provoke pitting corrosion on the steel alloys. Some organic compounds have shown good inhibitor properties to protect steel against corrosion in acidic media * E-mail address: metwally552@hotmail.com [1][2][3][4][5][6][7]. The existing data show that those compounds act by a mechanism of adsorption on the metal surface.…”

Guar gum was tested as corrosion inhibitor for carbon steel in 1 M H 2 SO 4 solution using weight loss and Tafel polarization techniques. The results showed that the inhibition efficiency increases with the increasing of the guar gum concentration, which act as an inhibitor of the mixed type. The inhibition action of guar gum was discussed in terms of its horizontal adsorption on the metal surface. The adsorption follows Langmuir adsorption isotherm. The effect of the presence of chloride ion in pitting corrosion was analyzed by the potentiodynamic anodic polarization technique. The pitting corrosion potential changes with the concentration of Cl -ion according to a sigmoid S-shaped curve. This behaviour was explained on the basis of the formation of passivatable, active and continuously propagated pits.

“…Corrosion problem occurs in many industries, and can cause disastrous damage to metal and alloy structures causing economic consequences in terms of repair, replacement and product losses. Hence, various corrosion protection technologies have been employed, among them; the use of inhibitors is one of the practical methods for preventing corrosion of MS especially in acid media [2]. A wide variety of corrosion inhibitors ranging from rare earth elements [3] to organic compounds [4][5][6][7] have been used.…”

Background A new class of nicotinamide derivatives viz., N-((1H-pyrrol-2-yl)methylene)nicotinamide, N-((methyl-(phenyl)amino)methylene)nicotinamide, N-nicotinoylbenzimidothioic acid and N-(4-(methylthio)benzylidene)nicotinamide have been synthesized and their corrosion inhibition effect on mild steel in 0.5 M HCl was investigated by mass loss, Tafel polarization technique and AC impedance measurements. Results The inhibition efficiency of the inhibitors on mild steel in 0.5 M HCl has been studied based on concentration, time interval and temperature. Potentiodynamic polarization studies showed that all the examined inhibitors suppress both anodic and cathodic process and behave as mixed type of corrosion inhibitors. Conclusions The adsorption of all the inhibitors was found to obey Langmuir isotherm model. Electrochemical impedance data revealed that polarization resistance (R P ) increases and double layer capacitance (C dl ) decreases as the concentration of the inhibitors increases. FTIR, EDX and SEM analyses were performed to study the film persistency of the inhibitors.
