With the development of the materials sustaining the lubricating properties under the severe environmental conditions, solid lubricants such as MoS2 and graphite are coming into use. On the other hand, new type composite materials and polymer materials appear, for the power transmitting devices material. Thus, it is necessary to study the lubricating properties of solid lubricants of New Ceramic. The fibre of K2Ti6O13 breaks easily along with its tunneling structure of crystal lattice and bears in the perpendicular direction, which, in lowering the friction coefficient, is similar to MoS2. But, this tunneling structure is different from the formal layer structure, and it is worth examining whether this crystal. lattice can lower the friction coefficient or not.
