Fatigue Crack Initiation from Pitting Introduced during the Anodising Process
Abstract
This report discusses four examples of Australian Defence Force aircraft components manufactured from aluminium alloys that exhibited surface pitting arising from the anodising process. In three of the examples, the anodising pits acted as initiation sites for fatigue cracks, which ultimately led to failure of the components. The information presented in this report highlights the issue of anodising pitting and the associated potential for fatigue cracking which can extend to entire batches of anodised components.
