GALVANIZE
Definition
Galvanizing consists of covering a metal part by electrolysis with a thin layer of another metal, to protect it from oxidation and corrosion, or to give it a decorative appearance.
Metals used
The most common covering metals are zinc, nickel, rhodium, gold or silver. The choice depends on the desired effect: protection, surface hardness, or decorative appearance.
Parts concerned
In watchmaking, it is common to galvanize a dial or a movement. The process applies equally to functional components and to visible elements of the finished product.
Why galvanize in watchmaking
A movement comprises numerous parts in steel or brass, sensitive to corrosion. Galvanizing protects them, while also dressing certain visible components, such as bridges or screws, with a gilded, rhodium-plated or nickel-plated finish that contributes to the aesthetics of the movement.
Distinction from zinc coating
It is possible to obtain a zinc film without electrolysis, simply by dipping the part in molten zinc. In this specific case, the correct term is no longer to galvanize but to zinc-coat, as electric current is not involved.
