Corrosion Inhibition of 6063 Aluminum Alloy in 0.5 M Sodium Hydroxide Medium by Aqueous Extract of Seeds of <i>Garcinia</i> <i>indica</i>

Abstract

The corrosion inhibition of Garciniaindica extract (GIE) on 6063 aluminum alloy was investigated in 0.5 M sodium hydroxide (NaOH) solution by weight loss method and Tafel polarization techniques. The effects of inhibitor concentrations, temperature on the inhibitor action were investigated. Inhibition efficiency was found to increase with increase in concentration of inhibitor and it increased with increase in the temperature. The kinetic parameters and thermodynamic parameters were calculated. The adsorption of GIE was found to be through chemisorption and obeyed Langmuir adsorption isotherm.

“…Thus the coriander is considered as member of the Apiaceae family, is among most widely used medicinal plant, possessing nutritional as well as medicinal properties. The Coriandrum is widely reported in literature as green corrosion inhibitor for several metals and alloys like aluminum, mild steel, 6063 aluminum alloy, and carbon steel [40][41][42][43] .…”
