Special Issue Information

Dear Colleagues,

Micro-/nano-fabrication is a node processing technology. It refers to the design, processing, assembly, system integration, and application of submillimeter, micron, and nano-scale components and systems composed of these components. It integrates advanced technological achievements such as advanced tools for nanolithography, dry etching, and thin film deposition, additive manufacturing, optics, nano-electronics, computer micro-chips, sensors, and materials science. Currently, the main drivers for this technology are advanced micro-chips, micro-electromechanical systems (MEMS), and nano-electromechanical systems (NEMS).

Within these systems, the surface plays an important role. Different surface micro-/nano-structures can exhibit interesting functions. The development of high-quality micro-/nano-structures and devices with specific surface functionalities is increasing. At present, the development of functional micro-/nano-structures and devices, such as metamaterials, metasurfaces, flat optics, superwetting surfaces, anti-reflection (moth-eye ones) structures, and other structures or devices is still limited by micro-/nano-fabrication technology. Therefore, this Special Issue focuses on extensive and in-depth studies of surfaces and their functionalities arising from different micro-/nano-fabrication techniques. We hope this Special Issue will provide some references for the improvement of the processing capacity and efficiency of micro-/nano-fabrication technology in the future, as well as the key directions of future research.

NiP coating has excellent physicochemical properties and is one of the best materials for coating optical components. When processing NiP coatings on optical components, single-point diamond turning (SPDT) is generally adopted as the first process. However, SPDT turning produces periodic turning patterns on the workpiece, which impacts the optical performance of the component. Magnetorheological finishing (MRF) is a deterministic sub-aperture polishing process based on computer-controlled optical surface forming that can correct surface shape errors and improve the surface quality of workpieces. This paper analyzes the characteristics of NiP coating and develops a magnetorheological fluid specifically for the processing of NiP coating. Based on the basic Preston principle, a material removal model for the MRF polishing of NiP coating was established, and the MRF manufacturing process was optimized by orthogonal tests. The optimized MRF polishing process quickly removes the SPDT turning tool pattern from the NiP coating surface and corrects surface profile errors. At the same time, the surface quality of the NiP coating has also been improved, with the surface roughness increasing from Ra 2.054 nm for SPDT turning to Ra 0.705 nm. Full article
