Product Description

The hard material coatings chromium (Cr) and chromium nitride (CrN) optimallyprotect engine components such as piston rings against premature wear and consequently extend the useful life of important engine parts. Chromium is used as a bonding layer for DLC coatings (Diamond Like Carbon), for example on bucket tappets. Furthermore, when used as a decorative coating, our chromium gives watches, electronic goods, operating elements on appliances and a range of other products an attractive sheen.

Furthermore, when used as a decorative coating, our chromium gives watches, electronic goods, operating elements on appliances and a range of other products an attractive sheen.

Decorative chromium coatings are applied using the magnetron sputtering method. Wear resistant and adhesive layers can also be produced using the arc evaporation method.


We supply rotary and planar arc cathodes as well as planar sputtering targets in the quality variants High Purity (HP) and Ultra High Purity (UHP):
