A simple, cost effective method for producing carbons with high mesopore contentis presented. The effect of the ratio activating agent (ZnCl2) to carbon precursor (coconut shell) on pore size is investigated as nitrogen adsorption isotherm these carbonaceous materials at 77 K. mesoporosity substantiated by absorption capacity phenol, methylene blue, and erythrosine red. Mesoporous high-surface-area activated carbons, which up now have proved difficult prepare, applications catalytic, battery...
Epoxy-based composites reinforced by three-dimensional graphene skeleton (3DGS) were fabricated in resin transfer molding method with respect to the difficulty good dispersion and arrangement of sheets directly mixing epoxy. 3DGS was synthesized process self-assembly reduction poly(amidoamine) dendrimers. In formation 3DGS, ordered state, which resulted exceptional mechanical properties thermal stability for epoxy composites. For 3DGS/epoxy composites, tensile compressive strengths...
The electrochemical behavior of thermally sprayed Zn–Cu–Ti coating corroded in 3.5 wt% NaCl neutral salt spray for different days was investigated by measurements. Electrochemical investigation shows that pitting corrosion occurs on the coating. Sacrificial anode protection and product play a dominant role. Coating can be divided into five stages: dissolution surface oxides, deposition products, stable coating, formation development occluded cell corrosion, accelerated stage. degradation...
Purpose This study aims to enhance the corrosion resistance of Zn-Al coating by synthesizing ZIF-8/LDH composite films. Design/methodology/approach LDHs films were synthesized via hydrothermal method, followed preparation through coordination substitution. Characterization was done using X-ray diffraction, electron probe microanalysis, atomic force microscopy and transmission microscopy. Corrosion evaluated electrochemical impedance spectroscopy polarization curves in 3.5 Wt.% NaCl solution....
Abstract In the present study, Zn–0.3Cu–0.3Ti alloy (sample I) was fabricated by a simple low‐temperature melting method using Cu–50Ti amorphous ribbons for corrosion in 3.5% NaCl solution. As comparison, crystalline master used to prepare II). Sample I comprising Zn, TiZn 3 , and 15 phases exhibits an equiaxed microstructure with subgrain structure. Large particles show cluster feature, whereas intermittent small exist at grain boundaries boundaries. sample II, Zn matrix typical dendritic...
In this paper a bonding-FSSW hybrid method is proposed and the joining procedure as well microstructure performance of joints AZ31 aluminum alloy examined . The results show that bonding agent has little influence on forming mechanical property FSSW nugget, shear-resisting with sealing glue equivalent to joints, in joint high-strength agent, are apparently superior pure or joints. Tiny uniform equiaxial grains formed WN(Welding nugget zone) coarse TMAZ (Thermomechanically affected HAZ (Heat...
Bridge cables composed of 1960 MPa steel wires can be damaged during vehicle fires. Therefore, it is necessary to study the high-temperature mechanical properties under load-bearing conditions. In this paper, and microstructure wire after stress relaxation annealing treatment at different temperatures are investigated. The results show that limit 422 325 °C. tensile strength 1975 MPa, which decreases by 5.73% compared with initial state. When temperature 300 °C, 2044 accounting for 98.7%...

Abstract ZnOHF/ZIF‐8 (Zeolitic Imidazolate Frameworks‐8) composite with a thickness of about 13.4 μm was coated on Zn–Cu–Ti alloy via hydrothermal route for the first time and its corrosion resistance performance investigated in 3.5% NaCl solution. It is found that I corr composite‐coated (7.03 × 10 –4 A/cm 2 ) lower than substrate (12.47 ). Meanwhile, shows higher product 121.2 Ω cm comparison (102.2 Moreover, after 6 days immersion, exhibits layer thickness. Its coating only 42.5 μm, but...
