The research investigates the corrosion of aluminium, aluminium-silicon and aluminium-zinc coatings on steel, comparing their corrosion resistance with that of galvanised steel. The history of coatings on steel for corrosion control is briefly recounted. The theory of metallic corrosion, and the corrosion of the metals under test, is reviewed. The experimental programme comprises humidity, salt spray and kesternich cabinet tests, immersion tests, tests of the materials subjected to shallow submersion in moving electrolytes, atmospheric corrosion tests, and electrochemical tests in different solutions, including coupled and potential-time tests. The research was carried out as a Cooperative Award in Science and Engineering with a firm experiencing corrosion problems in the use of coated steels as cladding materials in farm animal buildings. Consequently investigations were also made into the corrosiveness of the atmosphere in animal buildings, and the types of corrosive attack experienced with coated steels in such an environment. In conclusion mechanisms of corrosion are proposed for aluminium and aluminium-silicon coatings on steel, and the relative corrosion resistances of the coated steels under test are given.
