This paper presents a probe-based force-controlled nanoindentation method to fabricate ordered micro/nanostructures. Both the experimental and finite element simulation approaches are employed to investigate the influence of the interval between the adjacent indentations and the rotation angle of the probe on the formed micro/nanostructures. The non-contacting part between indenter and the sample material and the height of the material pile-up are two competing factors to determine the depth relationship between the adjacent indentations. For the one array indentations, nanostructures with good depth consistency and periodicity can be formed after the depth of the indentation becoming stable, and the variation of the rotation angle results in the large difference between the morphology of the formed nanostructures at the bottom of the one array indentation. In addition, for the indentation arrays, the nanostructures with good consistency and periodicity of the shape and depth can be generated with the spacing greater than 1 μm. Finally, Raman tests are also carried out based on the obtained ordered micro/nanostructures with Rhodamine probe molecule. The indentations arrays with a smaller spacing lead to better the enhancement effect of the substrate, which has the potential applications in the fields of biological or chemical molecular detection.

“…The laser surface texturing operation process is simple, non-toxic, non-polluting, high stability, and can handle a wide variety of materials, which has great advantages in superhydrophobic surface preparation [13,14]. In the research that has been carried out, most of the work uses picosecond and femtosecond lasers [15,16,17,18].…”

Fabricating the Superhydrophobic Nickel and Improving Its Antifriction Performance by the Laser Surface Texturing

et al. 2019

The superhydrophobic surface can change the friction property of the material, reduce the adhesion of the friction interface, and produce a certain slip, thereby reducing the friction coefficient. The laser has high energy, high density, and is especially suitable for the surface treatment of materials. The laser surface texturing is a good way to construct superhydrophobic surfaces. The experiment uses a nanosecond pulse laser to construct the groove texture on the nickel surface. The contact area between the air and the droplets retained on the rough surface is increased, effectively preventing the water droplets from entering the gully of the surface microstructure, reducing the water droplets and the solid surface. The contact area ultimately makes the surface exhibit excellent superhydrophobicity. A superhydrophobic nickel surface having an apparent contact angle of water (ACAW) of 160° and a sliding angle (SA) of less than 10° was prepared. The MM-W1B vertical universal friction and wear tester was used to test the groove texture samples with different depths. The surface texture can capture the wear debris generated by the wear and store the lubricant, which is beneficial to the formation of fluid dynamic pressure lubrication and improve the load. The friction coefficient is reduced from 0.65 of the unprocessed surfaces to 0.25 after the texturing, and the friction performance is greatly improved.

“…Surface texturing is a promising approach aiming at modifying friction and wear properties by introducing well‐defined textures. It is well‐known that precisely defined and well‐selected textures are able to build‐up a hydrodynamic pressure, to store lubricant and/or wear particles as well as to reduce the real contact area, thus beneficially affecting friction and wear in different lubrication regimes . Apart from a potential friction and wear reduction, it has been reported that friction can be increased by surface texturing when using properly selected structural parameters …”

“…Apart from structural parameters, several studies have pointed out that the texture's shape has a tremendous impact on the resulting frictional behavior under dry and lubricated conditions . In order to fabricate well‐defined surface textures, a broad range of methods including embossing, etching, laser‐based technologies, and diamond cutting can be used. In this context, laser surface texturing (LST) has proven to be a powerful technique to fabricate periodic surface textures with feature sizes on the micron scale with a high precision, accuracy and homogeneity on various materials …”

Laser surface texturing is a powerful tool to fabricate functional surface textures, whereby their morphology and cross-sectional profile greatly depend on laser parameters such as pulse duration and fluence. In this work, the authors fabricate well-defined groove-like textures on stainless steel by laser surface texturing using different pulse durations ranging from nano-to femtoseconds, while keeping structural parameters such as depth and periodicity fairly constant. By doing so, the influence of the pulse duration on the resulting cross-sectional profile of the textures and its subsequent impact on the tribological response are assessed. Reciprocating ball-on-disk tests and computational fluid dynamic simulations with Abaqus are used to evaluate the tribological performance of the as-fabricated textures. Their results demonstrate that the use of laser pulses with different pulse durations induce changes in the resulting cross-sectional profiles with the formation of rims/bulges well as the occurrence of recast phenomena and debris accumulation for nanosecond laser pulses. Decreasing the pulse duration significantly reduces the heat affected zone and the thermal damage, as well as avoided the formation of rims/bulges. Reciprocating ball-on-disk tests demonstrated that the differences in the cross-sectional profiles have a significant influence on friction and wear behavior of the textured surfaces.
