“…The bending strength was similar to pure quartz ceramics, and compression strength was significantly better than the 2.5D SiO 2f /SiO 2 , overcome the phenomenon of lower intensity in a certain direction of 2.5DSiO 2f /SiO 2 .Tensile strength is lower than 2.5DSiO 2f /SiO 2 composite materials, but can meet the needs of most weapon types. Therefore, the overall performances of needling SiO 2f /SiO 2 composite materials are lower slightly than 2.5D SiO 2f /SiO 2 composites, but obviously better than that of quartz ceramics [2]. And needling SiO 2f /SiO 2 composites have good toughness, and the manufacturing cost is reduced greatly.…”

With the development of military weapons, the demand of weapons is growing. But now 2.5 D silica fiber reinforced silica composites have long production period, high cost,which limited the production and schedule of weapons. This paper studied low cost manufacturing technology from two aspects of fiber preform weaving mode and molding process. The preforms were prepared with needling process.CT images of needling preform, thermophysical properties and mechanical properties and dielectric properties of needling silica fiber reinforced silica composites were studied inthis paper.The results showed that needling SiO2f/SiO2 composites had short production period and low cost, which had good mechanical properties.Tensile strength was 20.1MPa, compressive strength of XY direction was 88.3MPa,bending strength was 52.2MPa. Dielectric contant was less than 3.05 and dielectric loss was less than 8×10-3.

“…Magnesium alloys have highly chemical property and are prone to oxidation and corrosion in media, which greatly limits their development (Yuan et al , 2021). The wear and corrosion resistance of magnesium alloys are improved by surface modification technology, such as electroplating (Amaravathy and Kumar, 2019), spraying (Zhao et al , 2016), anodizing-induced (Cao et al , 2023) and micro-arc oxidation (MAO) (Yang et al , 2020). Researchers have found that MAO breaks through the voltage limitation of traditional anodizing-induced oxidation.…”

Purpose The purpose of this paper is to study the effects of voltage on microstructure and properties of micro-arc oxidation (MAO) ceramic coatings formed on AZ31B magnesium alloy under the constant current–constant voltage operation mode. Design/methodology/approach The wear and corrosion resistance of MAO coating on AZ31B magnesium alloy was studied by MAO in silicate electrolyte under constant current and constant voltage. Findings When the voltage is 360 V, the wear and corrosion resistance of AZ31B magnesium alloy is the best. Originality/value The wear and corrosion resistance of MAO coating on AZ31B magnesium alloy was studied by friction wear and electrochemical workstation.

Li2FeSiO4, as a highly promising polyanionic cathode material, has the advantages of high energy density, low cost, good thermal stability, high safety, and environmental friendliness. However, its electrochemical performance has been affected by such drawbacks as low electrical conductivity, low Li-ion diffusion rate, and crystal instability. In order to solve these problems and truly realize the commercial application of Li2FeSiO4 cathode materials, researchers have proposed more and more preparation or modification methods to optimize the electrochemical performance of Li2FeSiO4. This paper lists the electrochemical performance improvement of modified Li2FeSiO4 and its innovation potential. The realistic problems that still exist in the application of Li2FeSiO4 cathode materials at this stage are discussed. This paper provides a basis for the next innovative research and application of cathode materials for Li-ion batteries.
