Friction and wear performance of laser peen textured surface under starved lubrication

Abstract:We report on the effect of femtosecond-laser-induced periodic surface structures (LIPSS) on the tribological properties of stainless steel. Uniform periodic nanostructures were produced on AISI 304L (American Iron and Steel Institute steel grade) steel surfaces using an 800-nm femtosecond laser. The spatial periods of LIPSS measured by field emission scanning electron microscopy ranged from 530 to 570 nm. The tribological properties of smooth and textured surfaces with periodic nanostructures were investigated using reciprocating ball-on-flat tests against AISI 440C balls under both dry and starved oil lubricated conditions. The friction coefficient of LIPSS covered surfaces has shown a lower value than that of the smooth surface. The induced periodic nanostructures demonstrated marked potential for reducing the friction coefficient compared with the smooth surface.

“…Among these methods, laser surface texturing is considered as the most promising texturing technology. The main reason is that textures fabricated by LST could be precisely controlled and this process is friendly to the environment [9,10]. Experimental results in this filed shows that significant improvement can be achieved by laser surface texturing [7,[10][11][12][13].…”

“…In recent years, surface texturing has been successfully used in many applications to improve the tribological properties of sliding surfaces, such as piston rings, mechanical seals, hydro-static gas seals, journal bearings, thrust bearings, and soft elasto-hydrodynamic lubrication [9]. Fundamental research work on various forms and shapes of surface texturing for tribological applications has been carried out by several research groups worldwide and various texturing fabrication techniques have been employed, such as machining, ion beam texturing, etching techniques and laser texturing [10].…”

“…Because the lubrication film became thicker and the hydrodynamic lubrication region was expanded for dimple pattern texture, the lower friction coefficient was lower than that of groove pattern texture. Additionally, some investigations of modified surface under starved lubrication are carried out in last decade, such as laser texture on steel [20,21], copper [22], hard coatings [23], and piston ring-cylinder [24].…”

Grit blasting is one simple but effective method to modify the morphology of material surface and can improve the tribological performance. In this study, a thick TiN film was prepared by arc ion plating on the steel disk treated with grit blasting, and the rough surface coated solid film was obtained. The tribological properties of solid film against different materials were evaluated under starved lubrication regime. The results showed that the friction coefficients of rough titanium nitride (TiN) films were lower than those of rough steel disks exclude alumina ball under starved lubrication, and the wear rates of TiN film were negligible due to the high hardness of TiN film and small contact area. For four kinds of balls including steel ball, silicon nitride, zirconia, and alumina, the wear scar diameter of steel ball is biggest, and the wear scar diameters of other balls are small. The hardness of steel ball is less than others, which results in the easy abrasion and increases the contact area to reduce the pressure. So the friction coefficient of TiN against steel is low and steady.
