Abstract

Silicate-based corrosion inhibitor prepared by treating silica powder extracted from rice husk ash with concentrated alkaline. The electrochemical behavior of the Al 6061 immersed in 0.5 M hydrochloric acid (HCl) has been studied using the measurements of weight loss, potentiodynamic polarization and optical or scanning electron microscopy (SEM). It was found that, the optimum concentration of silicate-based corrosion inhibitor was prominent at 5 ppm. The small addition of silicate-based corrosion inhibitor was exhibited the decreasing of the weight loss of Al 6061 in acidic medium. SEM micrograph proved that the morphology of untreated Al 6061 with silicate-base corrosion inhibitor contributes more corrosion attack on sample compared to that treated Al 6061. The purpose of this research is to understand the effect of silicate-based corrosion inhibitor concentration yielded from rice husk ash on aluminum alloy.
