ABSTRACT:
The invention relates to a substrate covered at least partially with a layered coating. The layered coating comprises an intermediate coating and a hard carbon coating. The intermediate coating comprises a first metal layer deposited on the substrate, the first metal layer comprising at least one element of group IVB, group VB or group VIB; a nitride layer deposited on the first metal layer, the nitride layer comprising at least one nitride of an element of group IVB, group VB or group VIB; a second metal layer deposited on the nitride layer, the second metal layer comprising at least one element of group IVB, group VB or group VIB; a transition layer deposited on the second metal layer, the transition layer comprising at least one carbide of an element of group IVB, group VB or group VIB.
