Improving Tribological Performance Of Mechanical Seals By Laser Surface Texturing
Significant improvement in load capacity, wear resistance, friction coefficient, etc., of mechanical seals can be obtained by forming regular microsurface structure in the form of micropores on their surfaces. A feasibility study was performed experimentally using laser surface texturing (LST) technique to produce the micropores. Each micropore can serve either as a microhydrodynamic bearing in cases of full or mixed lubrication or as a microreservoir for lubricant in cases of starved lubrication conditions. Laboratory tests were performed, mainly with water, to investigate the potential of LST in mechanical seals. In all the tests, friction and face temperature were reduced, wear resistance was increased, and life was prolonged.
