Abstract

Experimental analysis has been advanced in the reduction of corrosion in various concentrations of hydrochloric acid (HCl) by compositional design. The analysis which involved metal matrix composite design and corrosion pattern determination by weight loss method and least square model showed that percentage weight loss, corrosion rates and reactivity decreased as Aluminum addition in the Al/Fe composite increases.  The evolved composite reaction in the media solution followed a first order equation pattern in which concentration decreases with time. With respect to the uncombined Iron (Fe) metal material, analyses showed that 30wt%Al/70wt%Fe composition reduced corrosion by 50% and is fairly sustainable and stable under severe harsh environment.

 

Key words: Weight loss, hydrochloric acid (HCl), corrosion.
