Subject: Corrosion on aluminum alloy

Corrosion on aluminum alloy

From: Sia Marshall <sia.marshall<-at->

I am planning a practical research project to try and find a
suitable chemical technique for removing corrosion from aluminium
alloy (navigation objects).  Phosphoric acid has been mentioned in
some conservation literature so I intend to investigate that first
by utilising coupon tests.

I am aware of the various corrosion inhibitors that exist for
aluminium but would prefer not to investigate these and instead
study chemicals with the potential to remove corrosion without
introducing further corrosion prevention.  The objects concerned are
small and stored in controlled conditions. Any comments or
suggestions will be most appreciated.
