“…These properties, including the area density, mean and Gaussian curvatures, have varying importance in an actual evaluation process depending on various applications of the workpiece. For example, the specific surface area distribution and fractal structure are mostly relevant for biochemical applications [24,25], while surface profiles, such as curvatures and normal vectors, have greater importance in optical microarrays [5,26]. The principal optimization objectives are similar: an adaptive scanning algorithm must include adequate faces to satisfy the performance evaluation of the reconstructed surface for certain applications.…”

In this paper, we present a novel geometry information-based adaptive step (non-equidistance) scanning path generation method for metrological scanning probe microscopes. This method reduces the total amount of required data and enables faster surface scanning speed for large industrial workpieces while preserving adequate geometric information for performance evaluation after surface reconstruction. The grid points are generated iteratively while gaining knowledge of the surface geometry step by step. We focus on the curvature properties and then propose a metric for the curvature information based on the triangulated surface geometry. With certain convergence criteria on the curvature measure variation, the proposed methods promise better surface reconstruction completeness and performance evaluation correctness. Simulations on the algorithm are performed on a typical parametric surface. A brief comparison to height-based scanning algorithm is performed to show the adaptability of the novel method on curvature evaluation. Experimental verifications are conducted to show the efficiency of the proposed algorithm.

For example, using the magnetron sputtering method, [21] nanoparticles were introduced on an Au-based MG surface. Based on nanoimprinting technology, [22] stripe patterns were introduced on an FeCo-based MG surface. Via thermoplastic forming, [23] nanopillars were prepared on a Pt-based MG surface.Although the above-mentioned methods can be used to fabricate micronano structures on MG surfaces, the processing efficiency and flexibility are far from satisfactory. Alternatively, owing to its advantages of no contact and high

“…For example, wettability transition from superhydrophilicity to superhydrophobicity has been achieved on various materials including aluminum [28], copper [29], stainless steel [30,31], and titanium [32][33][34][35][36] by combining laser surface texturing and lowtemperature annealing. In terms of laser texturing for BMG materials, there have been some recent research efforts on modification of surface properties of BMG via creation of laser-induced surface texture and change of surface chemistry [15,16,[37][38][39][40][41][42]. Huang et al utilized nanosecond pulsed laser irradiation to fabricate hierarchical micro/nanostructures on the Zr-based metallic BMG substrate in order to increase the effective surface area [16].…”

“…Jiao et al developed a nanosecond laser texturing technique to fabricate periodic surface structures, including dimples and grooves on Zr-based BMG surfaces [37]. They also investigated the effect of laser surface texturing on the wettability [15] and cytocompatibility [38] of the BMG surfaces. The modification of the surface wettability could be attributed to the laser-induced surface roughness and alteration of surface chemistry, and the enhanced cytocompatibility of the groove-textured BMG resulted from the combined effects of surface chemistry, wettability, and roughness.…”

Bulk metallic glass (BMG) has received consistent attention from the research community owing to its superior physical and mechanical properties. Modulating and controlling the surface functionalities of BMG can be more interesting for the surface engineering community and will render more practical applications. In this work, a facile laser-based surface texturing technique is presented to modulate and control the surface functionalities (i.e., wettability and hardness) of Zr-based BMG. Laser surface texturing was first utilized to create periodic surface structures, and heat treatment was subsequently employed to control the surface chemistry. The experimental results indicate that the laser textured BMG surface became superhydrophilic immediately upon laser texturing, and it turned superhydrophobic after heat treatment. Through surface morphology and chemistry analyses, it was confirmed that the wettability transition could be ascribed to the combined effects of laser-induced periodic surface structure and controllable surface chemistry. In the meantime, the microhardness of the BMG surface has been remarkably increased as a result of laser surface texturing. The facile laser-based technique developed in this work has shown its effectiveness in modification and control of the surface functionalities for BMG, and it is expected to endow more useful applications.
