Patent ID: 8002469

Claim:
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), Ti n-2 Cr 2 O 2n-1 with 6≦n≦9 and solid solution of TiO 2 —Cr 2 O 3 , 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.
