Abstract

 

This study was carried out to investigate and evaluate the electrochemical properties of mild steel (0.6, 1.0 and 1.46 mm), galvanized steel (0.36, 0.6 and 1.24 mm) and aluminium (0.9 and 1.3 mm) sheets exposed to cassava fluid. Corrosion rates of mild steel (10.595 mm/yr), galvanized steel (11.26 mm/yr) and aluminium (9.556 mm/yr) sheets exposed to cassava fluid were got using weight loss technique. The weight loss of each sample for specific periods of immersion (120,168,216, 264 and 312 h) was determined on average of two samples exposed under same cassava fluid in different plastic containers. It was found that aluminium samples had highest corrosion resistance followed by mild steel then galvanized steel. Also corrosion rates for all metallic samples studied decreased over the immersion durations.
