Abstract
Metal containing amorphous hydrocarbon films (Me-C:H) have excellent t ribological properties and an adjustable electrical conductivity. Fric tion force microscopy investigations on gold- and tungsten-C:H films s how a non-linear dependence of friction on the load in the nanonewton- range which can be explained by Hertz model of elastic contact. The ef fective friction coefficient and the interfacial shear stress strongly depend on the type of metal and the metal concentration inside the fi lm. Microfriction and macrofriction (pin-on-disk) show a high qualitat ive correspondence.
