Abstract

Corrosion inhibition effect of Areca catechu, Laurus nobilis and Catharanthus roseus plant extracts on mild steel was investigated in 0.5 M NaCl solution in open air at 28 ± 1 °C using immersion tests, inhibition mechanism and corrosion potential measurements. The corrosion rate of the steel was decreased with increasing the concentration of the extracts up to 2000 ppm. Catharanthus roseus plant extract was found to be most efficient inhibitor among the three extracts used in this study. Adsorption of all three plant extracts on the surface of the mild steel obeyed both Langmuir and Temkin adsorption isotherms. Areca catechu and Catharanthus roseus plant extracts acted as an anodic type corrosion inhibitor, while Laurus nobilis extract acted as mixed type inhibitor based on the potential measurement. Consequently, all the three plant extracts can be used as an environmentally friendly inhibitor to control the corrosion of mild steel in aggressive environments.
