“…The fractal structure channel located on the friction contact surface can inhibit the air reflux and promote the fluid flow in the contact area, which improves the lubrication and debris removal ability of the fluid, as shown in the Figure 23a 41,63 . In addition, fractal microchannels improve convective heat transfer capability by enhancing secondary flow during heat and mass transfer processes 42 .…”

Ceramic materials are widely used in engineering field because of their good physical and chemical properties. The poor mechanical properties of traditional ceramics seriously limit the development of ceramic materials and have attracted extensive attention since its birth. The development of high toughness, light weight, and functional ceramic materials has long been the pursuit of materials scientists. Since ancient times, nature has been the source of all kinds of human technological ideas, engineering principles, and major inventions. The functional structure of biology provides a good research object for the bionic design and preparation of ceramic materials. Therefore, it is necessary to summarize the functional structures and mechanisms in nature and biomimetic preparation technology. The purpose of this review is to provide guidance for the functionalized biomimetic design and efficient preparation of ceramic materials. Some typical functional examples in nature are introduced in detail, and several representative biomimetic preparation methods are listed. Finally, the performance and application status of biomimetic ceramics are summarized, and the future development direction of biomimetic ceramic materials is prospected.

For the purpose of optimizing grinding wheel profiles and grinding parameters, the prediction of the morphology of the grinding workpiece is essential. In this study, a new simulation model is developed to forecast the grinding workpiece surface morphology of ceramic material while accounting for the strain-rate effect. The effects of grinding parameters and patterned grinding wheel characteristics (e.g., grain geometry, grain size, grain protrusion height, and grain placement) on the surface and subsurface damage are explored. The results show that the simulation findings agree well with the theoretical approach, which takes the strain-rate impact into account. Additionally, the magnitude of the change in surface roughness increases as the properties of the patterned grinding wheel grow, whereas the magnitude of the change in surface roughness reduces as the grinding parameters increase. Furthermore, the grinding parameters have a greater impact on subsurface damage than the patterned grinding wheel options.

Tungsten carbide (WC) has been widely utilized in recent years in the hardware, mechanical, and chemical industries and in national defense because of its high hardness, anti-wear, low temperature, and anti-corrosion properties. However, using it for grinding is also challenging because the WC material has high hardness and brittle characteristics. The typical hub of a diamond wheel is made of steel. In high-speed grinding, the steel hub of the diamond wheel is subjected to gravity and centrifugal forces, which cause grinding wheel vibration, poor workpiece processing quality, and a short machine life. Therefore, this study used a carbon-fiber-reinforced thermoplastic (CFRP) hub to replace the steel hub when grinding the WC workpiece. It aimed to investigate methods to reduce oscillation, improve chip efficiency, and increase accuracy in the WC workpiece. The research results demonstrated that using a CFRP hub in the grinding wheel can reduce the oscillation when the peripheral speed of the grinding wheel is at 20–100 m/s. Additionally, the surface roughness average (Ra) of the workpiece can be reduced to 3.2–25.4% and the ten-point height of irregularities (Rz) can be reduced to 18.9–44% compared to using a steel hub in the grinding wheel.
