Abstract
This paper presents the experimental results of investigating the feasibility of new method to control the permeability of porous bushings used for aerostatic bearings. Sintered bronze discs are used as porous bushings, and their surfaces are irradiated with pulsed Nd:YAG laser to generate re-solidified layer which plays role as an air restrictor in the air feeding line. After above surface modification process, the change in air permeability of bushings is examined and the influence of irradiating conditions is also investigated. Then, a stability test and a stiffness test are performed to exam the effect of the re-solidified layer generated by surface modification process. The surface modified bushings have achieved high fluid resistance for air, and high stability of bearing. Furthermore, it is confirmed that the surface modification with laser has improve the static stiffness of thrust bearing with porous bushing.
