Abstract: A method of pre-treating articles of aluminium or aluminum alloy to form an environmentally stable adhesive receptive oxide layer, the method comprising anodizing said articles in a bath containing an aqueous solution of chromic acid at a minimum defined temperature/time/voltage cycle. By this method a particularly advantageous oxide surface layer is achieved in which the pore diameter of the outer, non-barrier layer is at least a factor of 10 larger than that achieved by prior art processes.
