Technical topics - "Corrosion of Aluminum"

George Thompson and Alison Daveport both from the Universities of Manchester and Birmingham, have done a lot of study regarding aluminium. Aluminium relies on a thin, adherent, intact, stable, and difficult to dissolve oxide. Recently, Douglas Mills, a technical secretary, worked with Bob Akid, that illustrate the pitting effect most effectively. In this study, electrochemical Scanning Probe Technique was used that showed up the nasty pitting quite well. The work also involved galvanic effects as well, a pure sandwich of pure aluminium clad onto aluminium alloy joined to steel. The aluminium also added to some high temperature alloys, forming an alumina scale which is stable.
