Effect of pH and salinity upon the corrosion rate of Marine vessel structure surface

Author(s): Al-Imarah Faris JM, Al-Hwaishim Inas Q
Abstract: In this study, a lab conducting experiments were performed for detecting corrosion behavior of mild carbon steel which is used in surface bodies of marine vessels. Corrosion for carbon steel was investigated by measuring the weight loss and hence the corrosion rate in four different media:1- tap water, 2- sea water, 3- acidified sea water, and 4- basified sea water. Those media were differ in their pH and salinity. The experiments were lasted for forty days, after that weigh loss were measured and corrosion rates were calculate, Moreover, the corroded metals in each media were measured by Atomic Absorption Spectrophotometer. The most effected surface was that immersed in acidic and saline medium which recorded the highest weigh loss of 2.344 mg and corrosion rate of 7.6684 mmy compared to 2.0124 mg and 3.073 mmy respectively for tab water medium.
