Abstract

Diamond-like ion-beam-deposited carbon (i-C) layers were obtained on WCCo cemented carbide using a mass-separated 12C beam at an energy of 500 eV and a deposition rate of 3 Å s-1. The mechanical properties of these layers were probed using microhardness and scratch tests and abrasive wear measurements. All these tests revealed that the depositions possess an extremely high hardness and good adhesion to the substrate. In particular, a hardness of 75 GPa was obtained, which is considerably higher than that found on i-C films involving hydrogen.
