in this paper, the effect of penicillin g drug as a green corrosion inhibitor on mild steel in 1.0 mhydrochloric acid solution has been investigated using potentiodynamic polarization, electrochemicalimpedance spectroscopy (eis) and electrochemical noise (en) techniques. the inhibition efficiencywas found to increase with increasing inhibitor concentration. potentiodynamic polarizationmeasureme...

The electrochemical corrosion parameters, such as potential, current density, and the Tafel constants are necessary inputs for modeling in reinforced concrete. Literature shows large variability their values, whereas data scarce carbonated This paper presents a range of parameters active steel passive noncarbonated Forty-eight singly concrete cylinders were cast, which 24 others sound samples. ...

Potentiodynamic Pt/C fuel cell catalyst corrosion has been studied as a function of chloride concentration with an electrochemical flow cell (EFC) coupled with highly sensitive ICP-MS. The Pt corrosion mechanism changes significantly: the anodic corrosion is much enhanced compared to the cathodic corrosion that prevails in electrolytes without Cl(-).

The inhibiting effect of drugs towards the corrosion of different metals and alloys has been reviewed in this paper. Results of Weight loss method, Potentiodynamic polarization and Electrochemical impedance spectroscopy were investigated. Kinetic and thermodynamic parameters provide valuable information about the mechanism of corrosion inhibition. Different classes of drugs, having hetero-atoms...

Additive manufacturing (AM) by laser powder bed fusion (LPBF) has gained significant research attention to fabricate complex 3D Inconel alloy components for jet engines. The strategic advantages of LPBF-based AM aerospace applications are well reported. exposed a high degree vibration during the operation in variable aqueous environment. combined and environment create tribological condition th...

In this paper, the effect of penicillin G benzathine (PGB) drug as a green corrosion inhibitor on mild steel in 1.0 M hydrochloric acid solution has been investigated using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The inhibition efficiency (IE) was found to increase with increasing inhibitor concentration. Potentiodynamic polarization measure...
