To address recent environmental issues on the lubrication in automobile engine, it is necessary to develop the alternative of the present sulfur- and phosphorus-based additives which poison any automotive exhaust catalysts. The "nano-carbon" materials, such as fullerene, nano-tube, and nano-onion, are expected to be used as the alternatives because they shown a good lubrication performance under boundary friction condition. Although many tribologists have studied their friction reduction and anti-wear mechanisms, there still remains unclear from the chemical point of view. Hence, in addition to the experimental studies, it is effective to use the computer simulation techniques such as molecular dynamics for the present issues. In this study, using experimental and computational chemistry methods, we investigated the boundary friction mechanism of nano-carbon materials which potentially alternate the present sulfur- and phosphorus-based additives.
