Corrosion and corrosion prevention of aluminium alloys in desalination plants: Part 2

Abstract

Velocity Velocity affects the kinetics of the dissolution of the protective film mainly. After the velocity has reached a critical level it may cause dissolution by erosion. Jet impingement tests have been devised to check the susceptibility of various materials to velocity. The corrosion of aluminium depends to a large degree on the sea water velocity. The corrosion rates of various materials in synthetic sea water having velocities from 2 to 16 m/sec at 20°C‐have been measured and with increased velocity the rate of corrosion was found to have increased and aluminium is not too much of an exception. About 2.3 m/s is the conventional agreed figure for aluminium and most users agree with it.
