Electrochemical and AFM studies on adsorption behavior of a Polynuclear Schiff Base at carbon steel in HCl medium

Abstract: The adsorption behavior of a potential polynuclear Schiff base, (s)-2-(anthracen-9(10H)-ylideneamino)-3-phenyl propanoic acid (A9Y3PPA) on carbon steel (CS) in 1M hydrochloric acid solution has been investigated using weight loss measurements, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization studies. The surface morphology of the carbon steel specimens in the presence and absence of the inhibitor was evaluated by AFM analysis. The corrosion inhibition efficiencies of parent amine a… Show more

“…6 Corrosion inhibition is a surface phenomenon where the adsorption of the organic and inorganic compounds on the metal surface serves as a means of achieving the aim. 7 There are various types of organic and inorganic compounds which have been studied as inhibitors for protecting metals against corrosion. In this scenario, Schiff bases are studied extensively due to the presence of >C]Ngroups which allow the corresponding Schiff bases to get adsorbed on the surface of mild steel and to form a monolayer on the surface spontaneously.…”

“…This is due to the interaction of ANHIS The decrease in the I corr value is more at high ANHIS concentration and high inhibition efficiency was obtained (93.12%) for 1mM inhibitor concentration. Furthermore, the addition of ANHIS did not change the value of E corr significantly (shift of E corr is less than 85) 42 which suggests that ANHIS inhibits both anodic and cathodic processes of corrosion (mixed type).…”

“…In three separate cases, AFM was used to test the external properties of 0.14%C steel materials, as seen in Figure 6 (a), (b) and (c) [55]. Figure 6(a) displays the surface morphology of the bare mild steel polished surface, while 6(b) and 6(c) reflect the MS specimen without and with an inhibitor, respectively.…”
