Effect of Epoxy/Al2O3/CeO2 Coating on Corrosion Rate and Mechanical Properties of Mild Steel

Abstract

In any industry like a power station, corrosion is a natural process that commonly happens and one of the problems that need to be considered. The example is in the underground pipeline where sea water is transported for cooling purposes. This study mainly on corrosion rate and mechanical properties of coating material on mild steel. Theoretically, Metal can get the higher rate of corrosion when exposed to the surrounding environment. Corrosion can cause to a lot of unwanted conditions, including failures in functions and higher maintenance cost as well as it is too risky for safety. The objective of this project is to study the corrosion rate and mechanical properties of the coating material of pure epoxy, aluminum oxide (Al2O3) and cerium oxide (CeO2) on mild steel. Different composition of epoxy/ Al2O3/CeO2 coating tested on mild steel specimen. There is three experimental conduct which is a Gamry test for corrosion rate and impact and hardness test for mechanical tests. As a conclusion, the results from the tests show that the coated mild steel of Al2O3-CeO2-epoxy obtained the best value in term of corrosion resistance and mechanical properties.

Production, structural and corrosion protection study of electroactive polyamide/alumina nanocomposites

“…Aperador et al [23] reported the hot corrosion resistance of Al 2 O 3 coating on the 316 SS substrate produced by thermal spray coatings with more polarization resistance for the coated sample than the substrate. Nasih and Vicki [24] have concluded that the mild steel coated specimen with epoxy/Al 2 O 3 /CeO 2 shows the lowest corrosion rate and reported that the intermolecular bond and adhesive strength was grater for Al 2 O 3 and CeO 2 containing coating than pure epoxy coating.…”
