ANTIFOULING PROPERTIES OF 90/10 COPPER-NICKEL ALLOY

The fouling of 90/10 copper-nickel alloys has been studied in the sea and in the Thames Estuary. Differences in fouling between these two sites and in the composition of corrosion products have been observed. In the sea, bacteria initially colonised the surface of the corrosion products and then became buried to form sheets of bacteria sandwiched between parallel corrosion layers. These corrosion layers are lined with bacterial mucilage which binds considerable amounts of copper. Further colonisation results in the development of slime films on the surface of the corrosion products. Evidence for the sloughing off of these and the slime film is presented and the success of the alloy in these environments is discussed.
