Abstract
N+ and C+ were implanted (30 keV, 10(17)-10(18) cm-2) into amorphous d iamond-like coatings (DLCs) produced by pulse-arc sputtering and into the substrates (stainless steel and hard tungsten-cobalt alloy) on whi ch the DLCs were deposited. Wear resistance of the implanted DLCs and that of DLCs on the implanted substrates were studied. It is shown tha t ion beams stimulate graphitization of the DLCs and thus make the coa tings weaker. By contrast, implantation of the ions into the substrate s enhances wear resistance of DLCs, thanks to an increase in the mater ial hardness under the coating and improvement of adhesion.
