Abstract

Divergences between the chemical compositions of the natural oxide layers on pure aluminium and of alloys containing magnesium have been shown with the aid of SIMS measurements. Scanning and transmission electron micrographs and electron microprobe measurements indicate the sensitizing effect of the thermal oxide layer to water vapour and this is substantiated by SIMS studies.

From published data and this investigation a further elaboration of the possible explanation for stress corrosion is proposed.
