Abstract
A tribological investigation of nanostructured carbon films performed with atomic force microscope is presented. Surface morphology is self-affine, wi th different correlation lengths corresponding to an inhomogeneous distribu tion of deposited carbon clusters. After reducing topographical effects, th e friction coefficient mu turns out to be similar to 0.15 (in air), with a slight dependence on the cluster distribution.
