The chemical composition of the deposited layers was determined using Raman, XPS, RBS and ERDA. Also the concentration of free radicals in the deposited layer was determined by EPR method. The thickness of the deposited carbon layer as a function of the deposition distance was determined by a scratch technique and AFM. Surface morphology of the samples was examined by AFM and nanointendation was used to determine microhardness and elasticity modulus and to perform scratch tests. The thickness of the deposited carbon layer decreases with increasing distance between the substrate and the filament. In addition to the dominant amorphous carbon fraction (a-C), various oxidized structures and hydrogen admixture in the deposited material were observed.
