Strategies for the replacement of chromic acid anodising for the structural bonding of aluminium alloys

demanding applications as a prebond treatment. This process has a number of
disadvantages and its replacement is the subject of much interest in the aerospace,
automotive and defence sectors, amongst others. This paper details a number of
modifications to the standard boric-sulphuric acid anodising (BSAA) process
specifically to achieve satisfactory structural bond performance. These included:
variations in the deoxidiser and anodising parameters, and; the use of a post anodising
dip. It has been demonstrated in these studies that there are three possible methods of
providing excellent durability using a variation of the standard BSAA process: the use
of an electrolytic phosphoric acid deoxidiser (EPAD); a high temperature anodise at
35°C, and; the use of a post anodise phosphoric acid dip (PAD).
