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