Abstract
A tribosystem for radial and axial foil bearings includes a first structural component part; and a second structural component part interacting with the first part. The first and second parts are in a dry frictional unidirectional sliding contact with one another until an air film is formed. A surface of at least one of the first and second parts being exposed to the dry frictional contact contains at least partly at least one of a metallic bound (Ti,Mo)(C,N), Tin-2Cr2O2n-1 with 6≦n≦9 and solid solution of TiO2—Cr2O3.

A tribosystem for radial and axial foil bearings, comprising:
- a first structural component part;
- and
- a second structural component part interacting with the first part, the first and second parts being in a dry frictional unidirectional sliding contact with one another until an air film is formed,
- wherein a surface of at least one of the first and second parts being exposed to the dry frictional contact contains at least partly at least one of a metallic bound (Ti,Mo)(C,N), Tin-2Cr2O2n-1 with 6≦n≦9 and solid solution of TiO2—Cr2O3, and
- wherein when a rotational speed of the second part exceeds a predetermined speed, air pushes the first part away from the second part, thereby creating the air film.
