<p>When a high areal pressure is applied to the interface between a member (1) and a member (2), a local solid contact takes place at the sliding interface to cause microscopic wear on the sliding surface of the sliding member. The sliding member (1) has a lubricating film (11), in which carbon-based molecules (12) are contained as separate molecules or as aggregates of the molecules. Due to the microscopic wear, carbon-based molecules (12) are exposed on the lubricating film (11), and part of the exposed carbon-based molecules are released therefrom and supplied to the sliding interface. Such carbon-based molecules (12) have a rollable hollow structure and hence function as a ball bearing of a molecular size at the sliding interface. The presence of at least one carbon-based molecule in this case can reduce the local friction as compared with the case where no carbon-based molecule is present. Consequently, not only a significant reduction in friction can be attained, but also mass-production is possible and a reduction in production cost can be attained.</p> |
