CORROSION BEHAVIOR OF ALUMINIUM ALLOY IN SEAWATER AT TWO DIFFERENT SITES OF KUALA TERENGGANU COASTAL AREA

An investigation on the corrosion behavior of aluminum at different sites of sea water in Kuala Terengganu was investigated. The method of corrosion assessment was by the use of potentiodynamic polarization scan (PP) and weight loss test. Aluminum alloy 1508 was employed in this study. This metal was immersed in seawater at different sites of Kuala Terengganu coastal area with different distance from the shore. Results obtained from electrochemical test techniques shown that lower corrosion effect of the metal significantly reduced the corrosion densities (icorr) and corrosion rate. The solution of seawater affects the corrosion rate according to their chemical and physical behavior of the sea water parameter
