The frictional properties of cobalt based diamond containing different size of diamond particles both in air and in vacuum were studied. In both cases a group of a metallic sliders were used. The coefficients of friction tend to increase with the increasing of the diamond particle size. The coefficient of friction in air is lower than that in vacuum. As a results of increasing the number of traversals, significant wear of the diamond composites by metallic sliders (stainless steel) was observed although the coefficient of friction was decreasing. Scanning electron microscopy studies revealed the wear track that and the wear debris formed during the friction tests. One of the significant factors for the reduction of friction could be the embedded fragmented diamond particle in the metallic sliders.
