Chains are chemically nickel plated and the nickel plating, among the protective siding, is the one that guarantees the highest oxidation resistance.
Chemical nickel plating allows you to get on all treated surfaces an uniform and continuous sediment, tight and highly resistant to corrosion and fatigue.
The deposits exhibit good adhesion to metal and moreover when there are mechanical damages of the carry they have a tendency to “peel”.
It’s also possible to perform an electrolytic nickel plating or as more commonly called “galvanic”, the metal is coated with nickel by a passage of electric current that carries atoms by bars of pure material to the material to be filled.
To increase the adhesion of the nickel to the metal and thus avoid the problem of peeling is deposited a layer of copper between the two materials.
