total hardness Germany

... DLC coatings have hardness values ranging from approximately 2000 to 3000 HV and are particularly characterized by very low dry friction coefficients of about 0.1 to 0.25 against metallic counterfaces, which they maintain even in inert atmospheres or under vacuum. They are applicable up to about 300°C, although the friction coefficient may increase above 100°C depending on the application conditions.
