Silicon carbide (SiC) is widely used to improve the non-linear conductivity of resistive field grading composite. In this paper, SiC nanoparticles are modified into core-shell with silica (SiO2) coating on surface and characterised by transmission electron microscopy X-ray diffraction, respectively. The 7 wt% [email protected]2/epoxy nanocomposite then prepared, pure epoxy SiC/epoxy prepared as...

Silicon carbide (SiC) has been widely used in many applications, which require high mechanical endurance or electrical resistance. It also serves as a basic material for light emitting diodes. Here, we present an in-liquid plasma method to produce SiC nanoparticles. A sustained spark-discharge dielectric liquid, is energized by nanosecond pulsed power supply, established the synthesis. To provi...

High specific strength and superior corrosion resistance are two key characteristics of the aerospace grade AA7075-T6 alloy. However, surface behavior is found to be deprived, because its being prone fretting fatigue adhesive wear under dry sliding conditions. Thus, improvement with retention microhardness alloy required for increasing wider application. For this, isomorphous precipitates soft ...

In this paper, AA5250 aluminum sheets are reinforced with boron nitride (BN), silicon carbide (SiC), oxide (Al2O3), and vanadium (VC). The nanocomposites metal matrix manufactured using friction stir processing (FSP). A novel analytical comparison based on an assessment of mechanical, physical properties the cost materials was conducted to help engineers designers choose most economically feasi...

β-SiC-supported cobalt catalysts have been prepared from nitrate, acetate, chloride and citrate salts to study the dependence of Fischer–Tropsch synthesis (FTS) on the type of precursor. Com/SiC catalysts were synthetized by vacuum-assisted impregnation while N2 adsorption/desorption, XRD, TEM, TPR, O2 pulses and acid/base titrations were used as characterization techniques. FTS catalytic perfo...

The aims of this study were to fabricate a novel titanium/silicon carbide (Ti/SiC) metal matrix nanocomposite (MMNC) by friction stir processing (FSP) and to investigate its microstructure and mechanical properties. In addition, the adhesion, proliferation and osteogenic differentiation of rat bone marrow stromal cells (BMSCs) on the nanocomposite surface were investigated. The MMNC microstruct...

This study aimed to improve the surface hardness and wear resistance of spindle hook teeth with special shapes reduce cost replacing on cotton pickers. For this goal, a Ni-Co-β-SiC composite coating different concentrations β-SiC nanoparticles (0, 1, 2, 3, 4 g/L) was electrodeposited teeth. The hardness, elemental composition, micromorphology were characterized by microhardness tests, an energy...

Room temperature cure epoxy resin has been doped with SiC nanoparticles through an ultrasonic cavitation process. The modified resin was then utilized in a Vacuum Assisted Resin Transfer Molding (VARTM) process with satin weave carbon fibers to manufacture nanophased composite panels. The nanoparticles were spherical in shape and about 29 nm in diameter. The loading of nanoparticles into the re...
