Abstract
Dalbergia latifolia and HCl: how they interact loss of mass at ambient temperature was used to evaluate corrosion in aluminium steel. Corrosion and inhibition were shown by weight loss method. Corrosion is reduced by increasing the concentration of inhibitors. Increased inhibitor concentration leads to better corrosion inhibition. The active site of aluminium steel is blocked and protected at higher doses of inhibitor solutions. The growth of the aluminium steel protective layer was evaluated in analytical experiments. This investigation employed alternating current impedance spectra and potentiodyna micpolarization. Subsequently, SEM and FTIR confirm these results. Smoothness on the external of aluminium steel were investigated using AFM both with and without an inhibitor after immersion in 1 M HCl. SEM tests the degree of surface smoothness in corroded, polished, inhibitor system aluminium steel.
