Abstract
SummaryThe corrosion resistance of light alloy semi-fabricated aluminium (Al 99·5 sheet and AGS extrusions), anodized and electrolytically coloured with nickel and copper salts, is studied. Results obtained after 38 months exposure in marine and industrial atmospheres have outlined the very good behaviour of films coloured with nickel salts and the less good performance of those coloured in black with copper salts, in particular when the sealing is not perfect. The paper also shows excellent correlation between the exposure at test sites, the CASS accelerated corrosion test results and the admittance values of the oxide layers, the last named permitting fairly accurate prediction of service behaviour.
