Sinkkikylpyyn

Sinkkikylpyyn, meaning "zinc bath" in Finnish, refers to a type of electroplating process used to coat metal objects, typically steel, with a layer of zinc. This protective coating is applied to enhance corrosion resistance, preventing rust and degradation of the underlying metal. The process involves immersing the item to be coated into an electrolytic solution containing zinc ions. An electric current is then passed through the solution, causing the zinc ions to deposit evenly onto the surface of the metal object.

This method is widely used across various industries, including automotive, construction, and manufacturing, for components such as fasteners, wires, and structural elements. The thickness and quality of the zinc coating can be controlled by adjusting parameters like current density, temperature, and the composition of the electrolyte. After the plating process, the object may undergo further treatments, such as passivation, to improve its appearance and further enhance its protective qualities. Sinkkikylpyyn is a cost-effective and efficient way to extend the lifespan and improve the performance of metal products exposed to potentially corrosive environments.
