Corrosion of ferrous alloys in deep sea environments

Abstract

Ocean has been studied. T he results of atomic absorption spectroscopy have revealed that E. S. DWARAKADASA the corrosion product present on mild steel coupons is FeOOH. T he results of ex periments M. RAVINDRAN in shallow water have shown that micro-and macrobiologicalgrowths play a signi cant role in the corrosion of ferrous materials. H owever, in deeper waters, the absence of macrofouling was evident, and corrosion was not related to any biological product but mainly to the electrochemicalreaction of these alloys with sea water. T he results of morphological studies by SEM on the surfaces of ex posed specimens are also presented.

The influence of the chemically bonded interface between fillers and binder on the failure behaviour of an epoxy coating under marine alternating hydrostatic pressure

“…However, harsh and complex conditions of deep ocean environment pose an enormous challenge to the corrosion protection of exploration facilities. One of the major factors is the hydrostatic pressure varying with ocean depth [1,2]. Employing organic coatings is one of the most widely used methods for protecting metals from corrosion.…”

Effect of hydrostatic pressure on the nature of passive film of pure nickel

“…Some natural ocean tests were reported by American [1][2][3][4], Russian [5,6], and Indian [7,8]. They revealed that materials undergo serious corrosion in deep ocean.…”
