Mechanism of adhesion failure of anodised coatings on 7075 aluminium alloy
7075 Aluminium alloys are used extensively in the fabrication of aircraft body parts and structural members. Most anodised products have an extremely long life span and offer significant economic advantages through maintenance and operating savings. Anodising is a reacted finish that is integrated with the underlying aluminium for total bonding and unmatched adhesion. However, this anodised layer may not adhere to the aluminium substrate resulting in excessive wear and corrosion. The cause of this type of coating failure was described in this paper and will be of great use to industry in which safety and length of service is paramount.
