Galvanisierung is a German term referring to the process of electroplating, also known as galvanizing when referring specifically to the application of a zinc coating to iron or steel. This electrochemical technique involves using an electric current to reduce dissolved metal cations so that they form a thin, coherent metal coating on an electrode. In the context of galvanizing, this process applies a protective layer of zinc onto a base metal.

The primary purpose of galvanisierung is to provide corrosion resistance. The zinc coating acts as a sacrificial anode, meaning it corrodes preferentially to the underlying metal, thus protecting it from rust and other forms of degradation. This makes it widely used for protecting steel structures, automotive parts, and various hardware components exposed to the elements.

The galvanisierung process typically involves immersing the object to be coated into an electrolyte solution containing ions of the plating metal. An electric current is then passed through the solution, with the object acting as one electrode and a source of the plating metal or an inert material as the other. Metal ions from the electrolyte deposit onto the surface of the object. The thickness and quality of the coating depend on factors such as current density, electrolyte composition, temperature, and immersion time.
