What is the approximate hardness of fork tube dlc coating?

1000-4000HV. fork DLC coating hardness is between 1000-4000HV, this hardness value is much higher than the fork without DLC coating treatment, of which, HV refers to the Vickers hardness, is a common test method of material hardness. DLC coating is a kind of drilling carbon film coating, with extremely high hardness, wear resistance and corrosion resistance, is one of the important technologies in the manufacture of high-end fork tubes. It is one of the important technologies in the manufacturing of high-end fork tubes.
