| Research Abstract |
We have studied correlation between the characteristics of tribofilm on a slider surface and the tribological properties of metal/diamondlike-carbon nanocomposite (Me-DLC) in which copper or silver were contained. The Me-DLC was prepared by the combined process between plasma enhanced chemical vapor deposition and direct current magnetron sputtering. The composition of the tribofilm was almost pure metal which is contained in Me-DLC. The nanoindentation measurements indicated that the hardness of the tribofilm was approximately 1 to 2 GPa, and load-dependent friction behavior was observed when the softer tribofilm forms on the harder slider surface.
