Zinc is probably the most widely used electroplating process. Its main application is corrosion protection. Zinc layers are subsequently chromatised, which massively increases corrosion protection.

Zinc processes can be found in practically every part of the world, as they are probably one of the most widespread galvanic processes. The main application is corrosion protection. Compared to practically all base materials, zinc is less noble and therefore behaves anodically. This means that when corrosion begins, zinc dissolves in favour of iron.

Zinc coatings are subsequently chromated, which massively increases the corrosion protection.

Zinc can be deposited using various processes. Although these result in the same coating properties (with variations in gloss), they are sometimes very different in terms of the bath composition.

In general, the requirements placed on the coatings are increasing and so these circumstances are taken into account, especially with zinc alloy coatings in the area of corrosion protection.
