摘要： PURPOSE: A foil bearing for turbo compressor is provided to achieve improved operation stability of compressor by preventing direct contact between the rotating shaft and foil and excessive abrasion of coating layer. CONSTITUTION: A foil bearing comprises a combination of a plurality of foils(20) which is shaped as a curved thin film. A high pressure gas film is formed between the surface of each foil and a rotating shaft, thus allowing the rotating shaft to be floated by the pressure of the gas film. Each of the foils has a coating layer(202) for preventing direct contact between the rotating shaft and the surface of the foil caused due to an excessive abrasion of the coating layer. The coating layer has a thickness gradually increasing as it goes from the center toward the peripheral area of the foil. Alternatively, the coating layer is formed into a stepped shape where the thickness of the peripheral area of the coating layer is larger than the thickness of the central area of the foil.
