Abstract:
Corrosion engineering is the application of science and art to prevent or control corrosion damage economically and safely. A corrosion must be well versed in the practices and principles of corrosion, the chemical, metallurgical, physical and mechanical properties of materials; corrosion testing; the nature of corrosive environments; the availability and fabrication of material; computer and design etc to perform their function properly. Percentage inhibition efficiency of CDEA as corrosion inhibitor at various concentrations (50, 100, 150, 200, 250, 300 and 350ppm) in 0.5M hydrochloric acid solution was determined by weight loss method at temperature 25°, 35° and 45°C. In addition of this, the micrographs of mild steel samples in 0.5N HCl solution with and without the optimal concentration of the CDEA as corrosion inhibitor were obtained at different temperatures. Results obtained from weight loss experiments show that CDEA acts as excellent corrosion inhibitor for mild steel in hydrochloric acid.
