Abstract
Corrosion is the degradation of the metal surface by the reaction with
its environment. In today’s circumstance corrosion is one of the major problem
in the industry and factories and other manufacturing sectors. The present work
investigates corrosion inhibition of mild steel in 1N HCl in presence of Hydnocarpus
pentandra seed (HPS) extract which is eco- friendly, biodegradable and does
not pollute the environment. Corrosion inhibition properties of (HPS) extract
has been examined on mild steel corrosion in 1N HCl solution by using
Phytochemical analysis, weight loss method, FT-IR analysis, SEM and EDAX
analysis. The result reveals that an increase in concentration of inhibitor,
decrease the corrosion rate and rate of degradation of the metal. The best
inhibition effect of HPS extract for mild steel was obtained by the weight loss
measurements up to 97%. Due to existing of various functional groups and
phytochemical constituents the inhibition efficiency increases and with
increase in the concentration of HPS extract. The surface morphology of
inhibited and uninhibited mild steel was investigated by scanning electron
microscope. The elemental composition was studied by the energy dispersive
x-ray analayis.
