DLC COATING WITH AN ABRADABLE LAYER

The present invention relates to a coating with resistance to wear, wherein first a DLC layer with a high degree of hardness is applied to a component and a gradient layer, the density of which decreases in the direction of the surface, is applied to said DLC layer. Owing to the hardness curve creat...

Beschreibung
Zusammenfassung:	The present invention relates to a coating with resistance to wear, wherein first a DLC layer with a high degree of hardness is applied to a component and a gradient layer, the density of which decreases in the direction of the surface, is applied to said DLC layer. Owing to the hardness curve created thereby in the gradient layer, the gradient layer functions as an abradable layer in applications with sliding surfaces.
