What is it about?

Zincating is a process that removes the surface oxide layer naturally present on aluminium and also leaves a surface coating of zinc. This permits a magnetically functional layer of nickel to be coated and strongly adhered to the underlying aluminium. The study explores different zincating treatments using electrical and microscopy techniques.

Why is it important?

The study provides insights into how coatings on computer memory storage media can be improved.

Perspectives

Techniques used include zinc immersion layers, double zincating, electroless nickel deposition, coating thickness measurements, scanning electron microscopy and atomic force microscopy. A free post-print version of the paper is available in the resources section (see right-hand-side panel).
