Description
In this study, aluminium material normally used in the underlie ship was immersed in simulated sodium
chloride environment and its degradation properties was evaluated. Investigation of corrosion rate and mass weight loss
through gravimetric tests measurements showed that less mass loss was recorded for tests in sodium chloride with 3-(2'-
chloro-6' fluorophenyl) and lowest corrosion rate values were found at 10%. On the other hand, the mass loss deteriorated
in all 3-(2'-chloro-6' fluorophenyl) with less uniform corrosion. The existence of chloride dissolved the interfacial surface
layer resulting into pit initiation and growth. It is found that corrosion degradation of aluminum is dependent on chloride
and inhibitive concentration
