Air-Foil Bearings are popular topics of research as a new kind of rotor support systems. Their specific construction brings a possibility of working with high rotational speeds at low power losses in a wide temperature range. Despite many advantages, Air-Foil Bearings meet problems of friction and wear in critical moments of their operation. The paper presents investigations of the materials which reduce an influence of undesirable effects.
