Abstract
We report role of sliding counterbodies which change the friction and wear properties of ultra nanocrystalline diamond (UNCD) film. Interestingly, SiC ball shows high value of friction coefficient ∼0.4 while low and ultra low values of friction coefficient are obtained using non carbon based ceramics and metallic counterbodies. Deviation in friction coefficient while changing the counterbodies is correlated to the contact adhesion of sliding interface. Origin of increased value of friction coefficient of UNCD films sliding against SiC ball is attributed to the presence of dangling covalent σ bonds of carbon atoms which possibly increase the adhesive force in the sliding plane.
