STUDY OF CORROSION INHIBITION PROPERTIES OF NOVEL SEMICARBAZONES ON MILD STEEL IN ACIDIC SOLUTIONS

The inhibition efficiency of corrosion on mild steel using acids by three different novel Semicarbazones as inhibitors have been studied using weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy methods. The inhibition efficiency, corrosion rate, the nature of anchor...
