Effect of Low Depth Surface Texturing on Friction Reduction in Lubricated Sliding Contact

Effect of Low Depth Surface Texturing on Friction Reduction in Lubricated Sliding Contact

Laser surface texturing is an interesting possibility to tailor materials’ surfaces and thus to improve the friction and wear properties if proper texture feature sizes are selected. In this research work, stainless steel surfaces were laser textured by two different laser techniques, i.e....
