Chromic acid anodising has been used since 1923 as a means of affording a level of corrosion resistance to aluminium alloys; the original method of anodising was patented by Bengough and Stuart and is still used today although more commonly a modified version is used. Recently, environmental pressure has resulted in alternatives to chromic acid anodising being sought. A key to finding a suitable alternative is to fully understand why chromic acid anodising affords a higher level of corrosion resistance compared with other forms of protection. The current research focuses on the pre-treatment and anodising of two aluminium alloys, AA 1050A and AA 2024T351, the film development process being investigated with the high purity 1050 alloy and the corrosion resistant properties afforded by chromic acid anodising investigated with the 2024 alloy.
