Title: Mass transfer effects of non-cavitating seawater on the corrosion of Cu and 70Cu-30Ni
Abstract: The present work is concerned with the prediction of corrosion rates of copper and cupronickel in flowing seawater (up to 16 m s−1) and for filmed copper and cupronickel (up to 3.5 m s−1). Such predictions are not available at present and would be of use for the design and maintainance of copper based components subjected to high velocity flows. Pipe systems on board ships often use such components—pumps, valves, elbows etc. The effect of flow on corrosion currents of filmed and polished samples that allows modelling of the behaviour of surfaces of old and newly fitted components is discussed. Equations describing the flow velocity dependence of these currents are developed and used to determine the mechanism controlling the copper dissolution and to identify the dissolution reactions.
