Specialized coating belonging to the DLC (Diamond Like Carbon) family
It is part of the DLC (Diamond Like Carbon) coating family.
It is made with electric arc technology and is composed of a Chromium Nitride adhesion layer and an amorphous Carbon layer.
The main features of this coating are a low coefficient of friction and a high chemical inertness, combined with good hardness values and an excellent adhesion to substrates.
It is produced at a temperature of 250 °C, which considerably extends its scope of application.
