Summary or description

The corrosion inhibition of 1018 carbon steel in 0.5 M H2SO4 was conducted by

using an organic extract of natural origin. The evaluation corrosion inhibition activity of

hexane extract of Allium sativum was carried out by electrochemical tests such as

polarization curves and electrochemical impedance spectroscopy. Different

temperatures were employed room temperature, 40° and 60° C. The inhibitor

concentrations were 0, 50, 100, 200, 400, 600 and 800 ppm. The organic extract acts

as corrosion inhibitor mixed and efficiency of corrosion inhibition increases linearly

concentration, the major efficiency of corrosion inhibition was up 90 percent used 400

ppm of A. sativum extract at room temperature. The efficiency corrosion inhibition is

affected by temperature increased.
