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.
