Effect of scanning speed and tin content on the

Femtosecond laser surface texturing of soft bearing materials such as tin bronze is of great interest to manufacturing community since it aims at protecting valuable steel components by reducing wear and friction. This paper examines the effect of scanning speed on femtosecond laser texture characteristics of tin bronze alloy containing 8% and 12% tin.

tribological behavior of laser textured surface. It goes on to investigate the influences of oil film thickness on formation of the coverage of oxides (Fig.1) and on the generated height of ridges/burrs (Fig.2). Analyses of experimental results suggest the possible reduction of the coverage area of metallic oxide Laser surface texturing of gray cast iron for improving Laser surface texturing process involves creation of microfeatures, e.g., tiny dimples, usually distributed in a certain pattern, covering only a fraction of the surface of the material that is being treated. The process offers several advantages for tribological applications, including improved load capacity, wear resistance, lubrication lifetime, and reduced friction coefficient.

Regular arranged micro-grooved textures with different spacing were produced on the AISI 304L steel surfaces by an 800-nm femtosecond laser. The tribological properties of smooth surface and textured surface were investigated

Modulation of dry tribological property of stainless steel

Regular arranged micro-grooved textures with different spacing were produced on the AISI 304L steel surfaces by an 800-nm femtosecond laser. The tribological properties of smooth surface and textured surface were investigated by carrying out reciprocating ball-on-flat tests against Al 2 O 3 ceramic balls under dry friction. Results show that the spacing of micro-grooves had a significant impact on friction coefficient of textured surfaces.
