AES Research Project #41: Plating on Anodized Aluminum; Part 3: Pore Structure and Bonding
The effect of anodizing voltage on the adhesion of nickel electrodeposited on anodized aluminum is related to the morphology of the anodic film. In general, adhesion is a linear function of the applied anodizing voltage. New data on the initial stages of pore formation during anodizing indicate that: (1) that the growth mechanism during the initial stage (< 10 sec) differs from that during subsequent growth, (2) there is no metallic bonding and (3) electrodeposited nickel coatings typically fill the entire pore.

AES Research Project #41: Part 4: Adhesion Failure of Electrodeposited Coatings on Anodized Aluminum Alloys
An SEM study of peel-test adhesion specimens from plated coatings on anodized aluminum shows that failure can be categorized in three different modes: (1) specimens exhibiting poor adhesion strength, which fail at the anodic film/coating interface; (2) specimens with good adhesion strength, which fail by local fracture of the anodic film and (3) specimens with excellent adhesion strength , which fail when the applied load is greater than the strength of the alloy substrate. The effect of anodizing parameters and alloy composition on peel test failure are discussed.
