To improve the corrosion resistance of biodegradable Mg alloys, WE43 alloys were implanted with Fe, Ti, Zn and Zr ions at same implantation dose. The surface morphology, valence state elements, nano-hardness (NH), elastic modulus (EM), degradation rate in vitro cell experiments modified systematically studied. A layer composed Mg, MgO, elements their oxides was formed on alloys. Since high-speed metal caused severe lattice damage, hardness substrate considerable increased. Electrochemical...
Zn−4Ag−Mn alloy was successfully prepared by high-pressure solid solution (HPS) method to achieve high strength and antibacterial implant materials which can degrade uniformly. Microstructural characterization showed that HPS treatment on resulted in 57.9% grain refinement, the average size of second phases reduced 10.2 μm compared with as-cast (AC) alloy. The compression, Vickers hardness wear friction tests particularly mechanical properties alloys, including a compressive yield 333.5 MPa...
Low hardness and poor wear resistance are major limitations of Al alloys, which hinder their application in several fields, especially automotive moving parts. DLC can effectively improve but high residual stress adhesion limit the film thickness. Multilayer thick films (~10 μm) composed alternating Ti Ti-DLC layers were successfully deposited on alloys. The influence content microstructure, mechanical tribological properties was emphasized. As decreased from 10.42 to 1.35 at.%,...
Graphene oxide–titanium (GO-Ti) composite materials were fabricated using GO as a precursor and then anchoring nano titanium (Nano-Ti) particles on sheets with the help of silane coupling agent. Then, coating samples prepared by dispersing GO, Nano-Ti particles, GO-Ti in an epoxy resin at low weight fraction 1 wt %. The composites investigated X-ray photoelectron spectroscopy (XPS), diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), transmission (TEM)....
Zinc (Zn) alloys have been paid increasing attention in the field of biodegradable implantable materials due to their moderate degradation rate compared magnesium (Mg) and iron (Fe) alloys. In this study, Zn–4Ag, Zn–4Ag–Cu Zn–4Ag–Mn were prepared investigate effects Cu Mn elements on microstructure properties Zn–4Ag alloys, addition improved mechanical The tensile strength Zn–Ag after rolling was increased from 141.9 MPa 168.4 206.3 Mn. 0.17 mm/year 0.22 0.39 first 5 days cytotoxicity...
Clarifying the electronic and magnetic properties of lutetium, lutetium dihydride, oxide is very helpful to understand emergent phenomena in lutetium-based compounds (such as room-temperature superconductivity). However, this kind study still scarce at present. Here, we report on metals, dihydride powders, powders. Crystal structures chemical compositions these samples were characterized by X-ray diffraction photoemission spectroscopy, respectively. Electrical transport measurements show...
AZ31 magnesium alloy sheets were fabricated by repeated bending−flattening deformation (RBFD) using dies of various angles. The microstructure evolution and behaviors the Mg during RBFD investigated FEM, OM, EBSD hardness tester. results suggest that 150°/150° die exhibits superior performance across all three groups. With an increase in passes, effective strain is significantly improved due to positive impact shear bending. After four average grain size can be refined 1.7 μm, a weaker basal...
Multilayers of Ti doped diamond-like carbon (Ti-DLC) coatings were deposited on aluminum alloys by filtered cathodic vacuum arc (FCVA) technology using C₂H₂ as a reactive gas. The effect different transition layer thicknesses the structure, mechanical and adhesion properties coatings, was investigated scanning electron microscopy (SEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), nanoindentation scratch tester. results showed that could improve interfacial between coating...
A high-performance BN@F-SiC filler was prepared by depositing hydrophobic nano-SiC grafted γ-aminopropyltriethoxysilane (KH550) and 1H,1H,2H,2H-trifluoro-noctyltriethoxysilane (FAS) on h-BN glycidoxy-propyltrimethoxysilane (KH560). coating containing 1 wt % composite dispersing the material in epoxy resin (EP), dispersion, wear resistance, corrosion electrochemical analysis, other tests were performed. Also, influence of SiC quality ratios these properties systematically studied. The results...
