A substrate (10) includes a metal diamond-like-carbon coating composed of a first layer (12) and second layer (14) deposited thereupon and having a thickness of about 0.5 micrometer to 10 micrometers. The first layer (12) is composed of a transition metal and has a first surface in contact with the substrate (10) and a second surface in contact with a second layer (14). The second layer (14) is composed of carbon and a transition metal selected from the group consisting of tungsten, niobium, titanium and combinations thereof. The metal-containing diamond-like- carbon coating compositions possesses an abrasive wear rate of no more than about 10 x 10 -15 m 3 m -1 N -1 .
