Galvanizacja

Galvanizacja refers to the process of applying a protective metal coating to another metal through electroplating. Typically, this involves immersing the object to be coated into an electrolyte solution containing ions of the coating metal. An electric current is then passed through the solution, causing the metal ions to be deposited onto the surface of the object. This forms a thin, uniform layer of the coating metal.

The most common application of galvanization is hot-dip galvanizing, where steel or iron is dipped into a bath of molten zinc. This process not only provides a protective layer but also creates a strong metallurgical bond. Another method is electrogalvanizing, which uses electrolysis to deposit a thinner layer of zinc or other metals.

The primary purpose of galvanization is to prevent corrosion. The coating metal acts as a barrier, protecting the underlying material from environmental factors like moisture and oxygen. In the case of zinc, it also provides sacrificial protection. If the coating is scratched, the zinc will corrode preferentially, sacrificing itself to protect the base metal. Galvanization is widely used in construction, automotive manufacturing, and for everyday items like nails, screws, and wire fencing. The durability and cost-effectiveness of the process make it a popular choice for extending the lifespan of metal products.
