    COMPARISON OF THE INHIBITION PROPERTY OF QUINOXALINE DERIVATIVE ON MILD STEEL IN 1.5M H2SO4, 3M HCL AND 1M H3PO4
    (Journal of materials and Environmental Sciences, 2017) Saranya, J; Sounthari, P; Chitra, S
    Corrosion inhibition of mild steel in 1.5M H2SO4, 3M HCl and 1M H3PO4 was investigated in the absence and presence of different concentrations of quinoxaline derivative namely 2,3-di(furan-2-yl)quinoxaline(FQ). Weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements were employed. Impedance measurements showed that the charge transfer resistance increased and double layer capacitance decreased with increase in the inhibitor concentration. Potentiodynamic polarization study showed that the inhibitor acted as mixedtype inhibitors in all the three acids.

    EXPERIMENTAL AND THEORETICAL STUDIES ON INHIBITION OF BENZOTHIAZINES AGAINST CORROSION OF MILD STEEL IN ACIDIC MEDIUM
    (Emerald Publishing Limited, 2017-05-02) Venkatesan, Hemapriya; Mayakrishnan, Prabakaran; Kandasamy, Parameswari; Subramaniyan, Chitra; Seung-Hyun, Kim; Ill-Min, Chung
    The aim of this paper was to investigate the corrosion inhibition potential of two synthesized benzothiazines, namely, 3,4-dihydro-2-methoxycarbonylmethyl-3-oxo-2H-1,4-benzothiazine (1) and ethyl 3-oxo-3,4-dihydro-2H-1,4-benzothiazine-2-carboxylate (2) on mild steel corrosion in 1M H2SO4.
