【Abstract】 The surface treatment to foil metal of aerodynamic gas bearing for high-speed turbomachinery was discussed in this paper. The choice of foil metal and the application of surface treatment, the start-stop cycle and the durable performance of foil bearings were experimentally studied. The test results indicate that the suitable choice of foil metal and the surface treatment method is very important to the durable performance of foil bearings.更多还原
