Proposal number EXAW-1999-01091
Proposal titleAn Environmetally Acceptable Chromate Replacement for the Passivation of
AbstractThe proposal addresses the replacement of toxic hexavalent chromate compounds in the
formation of passive films for corrosion protection on aluminium and its alloys. The aim
is to develop a low-toxicity replacement processing solution to give the level of corrosion
resistance and paint adhesion currently provided by chromate-containing formulations.
The objectives are to: (a) establish the most effective chromate-replacement for
passivating aluminium/aluminium alloy surfaces (b) optimise the treatment in terms of its
operating parameters e.g. treatment time, solution composition, pH, temperature (c)
develop the coating's characteristics in terms of adhesion of subsequent organic films and
(d) develop the process to a level where industrial specimens can be passivated in small
batch trials. passivated surfaces will be subjected to partner acceptance trials.
