“…As surveyed in [18][19][20], this LIPSS process is useful to make nanotexturing onto the punches and dies and to transcribe the tool-surface nanostructures onto the metal, polymer, and oxide-glass products by stamping. Optical property and structure control by femtosecond laser nanotexturing has a direct influence on the decoration on the metallic products [21,22]. In the present paper, the micro-/nano-textured AISI316 dies are fabricated by the femtosecond laser machining to coin the textured punch surface to the aluminum plate by CNC (Computer Numerical Control)-stamping.…”

The AISI316 austenitic stainless steel die was prepared and nitrided at 673 K for 14.4 ks. Through this low temperature plasma nitriding, the AISI316 die was homogeneously hardened up to 1400 HV within its surface layer of 50 μm. This nitrided AISI316 die was utilized to print the tailored micropattern with nanotextures onto its surface by the femtosecond laser processing. Each micropattern consisted of the tailored segments to have unidirectional nanotextures with different orientations. Each segment was recognized by its intrinsic surface plasmonic brilliance to tailored nanotextures. The CNC (Computer Numerical Control) stamping system was used to coin these micropatterns with nanotextures onto the AA1060 aluminum plates with the thickness of 1 mm. SEM (Scanning Electron Microscopy) and optical microscopy were employed to characterize the original micro-/nano-textures on the AISI316 die as well as the coined nanotextured patterns on the AA1060 plate surfaces.

“…Third, some stripes on the surface of WC grains are evidenced. These stripes are referred to as laser-induced periodic surface structures, and they are produced by the interference of the surface-electromagnetic waves induced by incident laser beams [35][36][37][38]. Fourth, coming back to the binder, it is observed that this phase becomes rather blurred due to its melting and incomplete vaporization.…”

Abrasive effectiveness of composite-like honing stones is related to the intrinsic surface topography resulting from the cubic boron nitride (CBN) grains protruding out of the metallic matrix. Within this framework, Laser Surface Texturing (LST) is implemented for replicating topographic features of a honing stone in a WC-base cemented carbide grade, commonly employed for making tools. In doing so, regular arrays of hexagonal pyramids (similar to CBN grains) are sculpted by a laser micromachining system. Micrometric precision is attained and surface integrity does not get affected by such surface modification. Finally, potential of laser-patterned cemented carbide tools, as alternative to conventional honing stones, is supported by successful material removal and enhanced surface smoothness of a steel workpiece in the abrasive testing.

“…For remanufacturing, the material and the contact pressure between the mating surfaces of fitting parts is difficult to be changed, so it can only be explored from the surface state. In recent years, surface texture [13], as a surface treatment technology, has exhibited a favorable tribological performance in piston rings [14], cutting tools [15], mechanical seals [16], and biomedical application [17]. Inspired by the fact that pit array textures has good anti-wear effect under the condition of dry friction [18], 5 different shapes of pit array textures are created on the specimens' surface, and the reduction effect of texture on the disassembly damage of interference fit is observed by orthogonal experiment.…”

After remanufacturing disassembly, several kinds of friction damages can be found on the mating surface of interference fit. These damages should be repaired and the cost is closely related to the severity of damages. Inspired by the excellent performance of surface texture in wear reduction, 5 shapes of pit array textures are added to the specimens’ surface to study their reduction effect of disassembly damage for interference fit. The results of disassembly experiments show that the order of influence of texture parameters on disassembly damage is as follows: equivalent circle diameter of single texture，texture shape and texture surface density. The influence of equivalent circle diameter of single texture and texture shape are obviously more significant than that of texture surface density. The circular texture with a surface density of 30% and a diameter of 100μm shows an excellent disassembly damage reduction effect. The load-carrying capacity of interference fit with the excellent texture is confirmed by load-carrying capacity experiments. The results show that the load-carrying capacity of the excellent texture surface is increased about 40% compared with that of without texture.
