Aluminum alloys corrosion microstructure effects

With galvanoaluminum coatings like zinc-nickel alloys, long duration times were reached. Regarding thermal and mechanical stress, the corrosion-protective effect of the zinc-nickel alloy layers is clearly inferior to that of galvanoaluminum. The short life span of IVD-aluminum deposits in comparison to galvanoaluminum is notable. This difference may result from the different microstructures of these two types of aluminum coatings [97, 156]. [Pg.219]
