Zinc coatings

Material and coating system: steel with a zinc-nickel layer of alloy
Damage profile: macrocracks
Cause of defect: probably caused by mechanical or thermal stress

Material and coating system: steel with a zinc-nickel layer of alloy
Damage profile: macrocracks
Cause of defect: probably caused by mechanical or thermal stress of the steel sheet

Material and coating system: free-cutting steel with a zinc coating.
Damage profile: base material particle (chip) partially enclosed by the coating
Cause of defect: probably caused by insufficient machining

Material and coating system: free-cutting steel with a coating of zinc-nickel alloy.
Damage profile: base material particle (chip) completely enclosed by the coating and without a visible bond to the base material
Cause of defect: probably caused by insufficient machining
