Paper Title:
Mechanical Seal Face Texturing by the Acousto-Optic Q-Switched Pulsed Nd:YAG Laser
  Abstract

Mechanical seal face texturing has the advantage of improving mechanical seal performance, such as improving opening force, reducing friction coefficient and minimizing wear and so on. In this paper, mechanical seal face, composed of sintered silicon carbon(S-SiC), is textured by the acoustic-optic Q-switched pulsed Nd:YAG laser in multi-mode. The micro-dimples are produced in mechanical seal face, and the profiles are measured by scanning electron microscopy (SEM) and 3D white light interference surface morphology apparatus. Results show that it is in the focus plane that maximal depth and minimum diameter appear and the circular profile of the micro-dimple can be acquired. And the diameter of micro-dimple increases with the increasing of single pulse energy reaching a saturation value at about 3.8mJ, but the increasing of single pulsed energy will reduce the depth of micro-dimple in a small range.
