A substrate having a multilayer coating system in the form of a surface coating, which has an outer cover layer comprising amorphous carbon, and a coating process for producing a substrate. At least a first MoaNx support layer is provided between the substrate and the cover layer, which support layer has a nitrogen content x, referred to an Mo content a, which is in the range of 25 at %≤x≤55 at %, with x+a=100 at %.
