Experimental Investigation of Laser Surface Texturing for Reciprocating Automotive Components
TLDR
In this paper, an experimental study is presented to evaluate the effectiveness of micro-surface structure, produced by laser texturing, to improve tribological properties of reciprocating automotive components, including piston rings and cylinder linings.Abstract:
An experimental study is presented to evaluate the effectiveness of micro-surface structure, produced by laser texturing, to improve tribological properties of reciprocating automotive components. The test rig and test specimens are described and some test results are presented. Good correlation is found with theoretical prediction of friction reduction on a simple, yet representative, test specimen. Potential benefit of the laser surface texturing under conditions of lubricant starvation is also presented. Finally, friction reduction with actual production piston rings and cylinder liner segments is demonstrated. Presented at the 57th Annual Meeting in Houston, Texas May 19–23, 2002read more

State of the Art in Laser Surface Texturing
TL;DR: Laser Surface Texturing (LST) is probably the most advanced surface texturing technique as mentioned in this paper and it produces a very large number of micro-dimples on the surface and each of these microdimples can serve either as a micro-hydrodynamic bearing in cases of full or mixed lubrication.
