Abstract
A laser polishing method for a metal face seal is provided. The method includes determining, using a processor, a first smoothness level of a seal face surface of the metal face seal. The method includes applying, using the processor, a laser beam at a first angle to at least one peak on the seal face surface of the metal face seal, the first angle measured relative to a normal to the seal face surface. The method includes determining, using the processor, a second smoothness level of the seal face surface. The method includes controlling, using the processor, the laser beam until the second smoothness level is equal to a threshold smoothness level. The method includes turning off the laser beam, using the processor, when the second smoothness level is equal to the threshold smoothness level isotropically over the seal face surface.
