Resumen
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.
