THE INFLUENCE OF FOULING UPON CORROSION RATES OF STEELS AND COPPER-NICKEL ALLOYS IN SEAWATER

The paper will present and discuss results gained from seawater exposure experiments and supporting laboratory studies of fouling/corrosion relationships on BS4360 grade 50d steel and various copper-nickel alloys. It has been found that fouling amassment is not significantly affected by surface finish of steel and corrosion rates reduce with time due to the formation of a partially-protective fouling/corrosion composite film. A model enabling prediction of corrosion rates of steel in seawater will be presented together with an expression enabling quantification of the effects of marine fouling upon corrosion rates of substrata. An explanation of the anti-fouling mechanism of copper-nickel alloys will be presented based upon results gained from studies on pre-exposed and cathodically-protected specimens. (Author/TRRL)
