摘要:
The sliding material of the present invention has hexagonal crystals that form a layer structure and ball-shaped molecules inserted in interlayers of the hexagonal crystals. This sliding material can be used in machines/devices of various sizes ranging from heavy machinery such as automobiles to nanomachines without restrictions on the environment it can be used, can minimize friction compared to conventional types, and has superior durability.
