Abstract
The literature on the corrosion of copper alloys in seawater published from 1975 to-date has been reviewed. The main topics covered are (i) the formation and nature of protective films (ii) velocity considerations (iii) corrosion in clean and polluted seawater with particular reference to sulphide pollution (iv) the effects of iron additions to cooling waters (v) other preventive or remedial measures. Other topics include the relationship between marine fouling and corrosion, sponge ball cleaning and the effects of chlorination. The applications in which the use of copper alloys has been of main interest are ships, power stations, desalination plants, offshore oil and gas rigs, with several potential new applications such as ships' hulls, fish cages and OTEC heat exchangers. It is concluded that good progress on many of these matters has been made in the last five years or so, though much remains to be done.
