Layer sequence and method of manufacturing a layer sequence

摘要

A layer sequence (400), comprising an aluminum layer (300), a nickel layer (301), and a nickel layer protection layer (302; 701). The aluminum layer (300) is formable on a substrate (200), the nickel layer (301) is formed on the aluminum layer (300), and the nickel layer protection layer (302; 701) is formed on the nickel layer (301).
