Corrosion and corrosion prevention of aluminium alloys in desalination plants: a review

Abstract

The aluminium alloys are rapidly gaining a worldwide attention because of the economical and technical advantages they offer in applications encountering marine and similar other aggressive environments. A list of such alloys is given in Table 1. Several factors such as high weight to strength ratio high thermal conductivity, satisfactory resistance to corrosion and the economic feasibility of these alloys make them attractive candidates for the next decade as against the conventional copper and nickel alloys. The economic consideration assumes even a greater magnitude when the requirements and the purchasing potentials of the third world are seriously considered. The good features of these alloys are to some extent counteracted by the necessity for environmental modifications required to overcome the potential hazards of corrosion such as pitting, galvanic corrosion, erosion‐corrosion, crevice corrosion, and others. The variation of sea water chemistry effects the kinetics of the dissolution of aluminium alloys largely.
