Electroplated coating

A galvanically applied coating is zinc, zinc alloy or other metallic coating which is deposited on a component or substrate by an electrolytic process. A reduction of the metal cations (e.g. Zn2+) is triggered in an electrolyte bath by means of direct current, so that the metal, i.e. zinc, is deposited on the component. The electrolytes used in this process are acidic or alkaline and are now largely cyanide-free. This process produces a uniform coating, which can be influenced by the time in the bath and the current strength. The use of zinc provides cathodic corrosion protection.  The process goes back to the Italian physician Luigi Galvani, who first investigated the effects of electric current on muscles and tendons in 1780. Since then, electroplated coatings - properly applied - have proven to be an efficient and proven corrosion protection system for many years.
