“…The relatively low porosity is largely due to the fact that extensive ZrC and SiC ceramic formation during the RMI process at 1900 C effectively fills both the large pores among the fibre bundles and some small apertures inside the fiber bundles. It is well known that, at a higher temperature, the fluidity of molten metal will increase since the viscosity decreases [27]. Thus, increasing the infiltration temperature facilitates the infiltration process and at the same time accelerates the reaction between the melt and carbon.…”

and SiO 2 , which covers the surface of the composites and retards the oxygen diffusion and the attack on the underlying C/C substrate. For SiC coated C/C composites, the large SiC particles formed on the surface of the composites are difficult to oxidize rapidly and so a continuous and dense SiO 2 layer cannot be formed in time to significantly hinder fast oxygen diffusion leading to the consequent severe oxidation of the C/C substrate.

“…The turns of the smaller coil transformed into an even smaller coil, and so forth until the elongation stopped, usually by solidification of the thin jet. [83] Bending/whipping instability is believed to be crucial in nanofiber formation via electrospinning. [65,80,81] Later, Fridrikh et al presented a model applicable to a charged liquid in an electric field with bending instability that predicted the diameter of a terminal jet.…”

Among currently available nanostructured materials, ultrafine nanofibers, carrying a range of novel physical and chemical properties, have attracted considerable attention in overcoming many limitations present in their corresponding macroscales. [14][15][16][17][18][19] Different strategies have been created and developed for nanofibers fabrication, including thermal-induced phase separation, drawing, template synthesis, and self-assembly, among which electrospinning is of considerable significance as a rapid, simple, and continuous process in manufacturing nanofibers, as well as formulating their 2D and 3D structures. [20][21][22][23][24][25][26] Besides, this straightforward, continuous, and cost-effective method can launch ultrathin nanofibers from an enormous number of materials, including polymers, inorganic ceramics, and composites. [27][28][29][30][31][32] Moreover, electrospun nanofibers and their assemblies are much more favorable in providing high specific surface area, large surface-to-volume ratio, tunable porosity with uniform pores distribution, and the ability of desired chemical functionalization for various applications. [33][34][35][36][37][38][39][40] This review aims to provide comprehensive and critical aspects related to recent developments in electrospinning Electrospinning, considered as a low-cost and straightforward approach, attracts tremendous attention because nanofibrous materials with functional properties prepared by it can be widely applied in numerous fields, including rechargeable batteries, filtration, and distillation. This paper aims to provide a comprehensive review of the latest advances in developing this unique technique, which starts with a brief introduction of the advantages of electrospinning and highlights ongoing research activities, followed by its principles and progress. Afterward, the corresponding properties of electrospun nanofibers are discussed. A future vision regarding challenges and perspectives in this area is proposed at the end. It is believed that this review would provide an extensive and comprehensive reference to utilize this advanced technique to generate novel nanofibers performing in high demanding areas.

In order to study the processing mechanism of jet electrodeposition and explore the influence of different scanning speed on the wear and corrosion resistance of nickel-based coating prepared by jet electrodeposition. The reciprocating scanning motion of the nozzle was used to prepare the nickel-based coating in a specific area. Combined with COMSOL software, the coupling effect of multiple physical fields in the process of jet electrodeposition at different scanning speeds was numerically calculated. Scanning electron microscope, microhardness tester, material surface comprehensive performance tester and electrochemical workstation were used to analyze the surface morphology, section thickness, microhardness, abrasion resistance and corrosion resistance of the nickel-based coating prepared by jet electrodeposition at different scanning speeds. Results show that with the increase of scanning speed, coating grain size decreases, and the coating thickness increases after the first decreases, and microhardness increase after decreases first, abrasion resistance and corrosion resistance were lower after increase first, When the scanning speed reaches 600mm/min, the jet electrodeposited nickel-based coating has the best performance, the maximum thickness reaches 24.83μm, the microhardness reaches 616.86HV, and the wear scar area is 2766.75μm2. In addition, the self-corrosion potential is -0.33V, the self-corrosion current density is 5.16E-7A·cm2, and the equivalent impedance is 4660Ω. The experimental results are consistent with the simulation results, which verifies the accuracy of the simulation model and provides theoretical guidance for further experiments related to jet electrodeposition.
