ABSTRACT:
The inhibition efficacy of the extract of Caesalpinia pulcherrima for the corrosion of mild steel in 1N hydrochloric acid was investigated by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and scanning electron microscope (SEM) techniques. The results indicate that CP flowers serve as a good corrosion inhibitor of mixed type with efficiency as high as 95% at 0.6% inhibitor concentration.
KEYWORDS:
