Abstract null null Low frequency noise has strong penetration power and is difficult to be attenuated. In order to solve the problem of low-frequency noise absorption in traditional sound absorbing materials, a coupled structure of coiled-up space core embedded in a porous material (CSPM) is proposed. The coiled-up space core (CSC) structure consists of a folding structure and a labyrinth structure, and a rectangular slot is cut at the top of each structure to allow the sound wave to enter. The ...

Abstract null null Ti6Al4V is often used in the manufacture of biomedical equipment due to its excellent properties such as light weight, high strength and good corrosion resistance in the physiological environment. Therefore, it is very important to form a non-toxic antibacterial surface on Ti6Al4V material. In this paper, a micro-nano manufacturing method of Ti6Al4V antibacterial surface was studied. In this process, the surface was firstly cut by low speed wire electrical discharge machine, a...

Carbon fiber-toughened silicon carbide composite matrix composite (Cf/SiC composite) occupies an important position in the field of aerospace due to its excellent mechanical properties. Because Cf/SiC composite have good high temperature resistance and hardness, machining traditional Cf/SiC composite is a difficult and time-consuming process. In this paper, two-dimensional braided Cf/SiC composite is used as the object, and a new laser-assisted machining orthogonal experiment system for processi...

Drilling is a kind of processing technology with a large proportion in mechanical processing, especially the drilling of deep hole, which is facing great challenges due to the high-strength properties of materials and debris-removal challenges. Because there is no obvious cutting force in the machining process and all conductive materials can be machined, microelectrical discharge machining (EDM) is playing an important role in deep hole drilling. In this study, micro-EDM technology was used for...

Severe plastic deformation occurs in micro metal cutting process; meanwhile, new surfaces are generated due to the material separation caused by ductile fracture. The energy required for the formation of the new surfaces is of kJ/m2, which should not be neglected in the analysis of micro-cutting. In this work, an analytical model is developed focusing on the analyses of the micro metal cutting process with no stable built-up edge, in which the effects of both edge radius and material separation ...

Abstract In this study, four bionic fish-scale models were extracted and produced based on the microscopic morphology and the arrangement of scales on the body of Sciaenops Ocellatus. A simple, quick and low-cost method using laser was introduced for fabricating the bionic fish-scale surface on aluminum (Al) alloy. Under the action of laser beams, the fish-scale morphology with inclined surface was obtained by controlling the density of laser path and processing times. Biomimetic fish-scale surf...

Design and fabrication of smart materials with reversible wettability for oil-water separation have attracted worldwide attention due to the increasingly serious water pollution problem. In this study, a rough oxide coating with micro/nanoscale structures is developed on the 304 stainless steel mesh (SSM) by laser ablation. The smart surface with ethanol immersion and natural drying treatments shows the wetting conversion between underwater superoleophobicity and superhydrophobicity. Based on th...

The slippery liquid infused porous surface has developed into a potential technology to solve the problem of poor durability in corrosion resistance. Herein, a kind of slippery liquid infused porous surface is created on 7075 aluminum alloy by wire electrical discharge machining for corrosion resistant applications. The hardness of the constructed porous microstructure is similar to the aluminum alloy substrate material, which ensures the stability of the slippery liquid infused porous surface. ...
