Abstract
The fouling of 90/10 copper nickel alloy was studied in the sea and in the Thames Estuary. Differences in fouling between these two sites and in the composition of corrosion products is reported. In the sea bacteria initially colonized 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 colonization results in the development of slime films on the surface of the corrosion products. In the Thames evidence for the sloughing off of these and the slime film is presented and the success of the alloy in these environments is discussed. (A)
