Abstract

Modified chicken feather reduced the corrosion rate of mild steel in drilling mud as deduced from electrochemicalpotentiodynamic polarization technique, albeit, with observed infestation of the test environment by microbesover protracted exposure period of 92 days. The corrosion rates with and without the addition of 0.3g ofhydrolyzed feather per 100 ml of drilling mud were 1.70 and 1.95 mm/yr, respectively; which corresponded toinhibition efficiency of 13% over the immersion period. The corresponding charge transfer resistances, a measureof corrosion rates were 1480.4 and 1780.0Ω, respectively; in the uninhibited and hydrolyzed-feather inhibitedenvironments. The voltage over the double layer capacitor as obtained from the polarization studies numericallyincreased from�0.907 to�0.948 V which indicated adsorption of moieties in the inhibitor and probably somecorrosion products on the surface of the mild steel specimen.
