The effect of laser surface texturing on frictional performance of face seal

Laser surface texturing technology has some advantages in reducing friction and wear of mechanical parts in industry. In this paper, a Nd:YAG laser was used to generate micropores on T8 steel surface and the structure and morphology features of surface micropores were observed. Tribological experiments were conducted with a ring-on-disc tester under various loads and speeds. It is shown that the maximum PV value of face seal can be increased by hydrodynamic effect of micropores.
