sinkkipäällystöissä
Sinkkipäällystöissä, often translated as zinc coating or galvanization, refers to a protective metal coating applied to steel or iron to prevent rusting. This process involves immersing the base metal in a bath of molten zinc. The zinc then forms a metallurgical bond with the iron or steel, creating a layered surface. The primary mechanism of protection is sacrificial, meaning that the zinc corrodes preferentially over the steel, sacrificing itself to keep the underlying metal intact. Even if the coating is scratched and the steel is exposed, the surrounding zinc will continue to protect the exposed area through galvanic action.
This method is widely used in construction, automotive manufacturing, and for everyday items like nails, screws,
