Electrocatalytic nitrate (NO3-)/nitrite (NO2-) reduction reaction (eNOx-RR) to ammonia under ambient conditions presents a green and promising alternative the Haber-Bosch process. Practically available NOx- sources, such as wastewater or plasma-enabled nitrogen oxidation (p-NOR), typically have low concentrations. Hence, electrocatalyst engineering is important for practical eNOx-RR obtain both high NH3 Faradaic efficiency (FE) yield rate. Herein, we designed balanced proton adsorption by...
Ti alloys are prone to corrosion and wear due the hostile environment in bodily fluids, but Ti-45Nb alloy is considered be a promising titanium with excellent biocompatibility resistance physiological corrosion. In this study, Nb ions were implanted into TA3 effect on biological as well tribocorrosion behavior of Ringer’s solution was systematically investigated. The surface microstructure XRD results revealed that samples showed smoother sputtering radiation damages, mainly existed solid...
Abstract Underwater gliders are winged, autonomous underwater vehicles that broadly applied in physical and biological oceanography. The position of the wing has an important effect on movement performance glider. In this paper, dynamic motion a series glider models with different longitudinal positions simulated, which provides guidance for design gliders. results show when net buoyancy is constant, affects gliding angle, but does not affect relationship between angle speed. addition,...
In this study, TC18 titanium alloy was ion implanted with Zr ions to a fluence of 3.56 × 1016, 5.53 1016 and 7.12 cm−2. The surface morphologies were characterized by the scanning electron microscopy (SEM) atomic force microscope (AFM). crystal structure evaluated x-ray diffraction (XRD) corresponding calculations used analysis nanoindentation behavior. Nanoindentation tests different loads (5 mN, 10 mN 15 mN) investigate behavior samples. implantation not only affected microstructures...
Abstract Titanium and titanium alloys are considered as good implant materials, but their poor tribocorrosion resistance limits further development. In this study, niobium coating (DG-Nb) was deposited on TA3 pure (Pure Ti) by double-glow plasma alloying aiming to improve the of Pure Ti. The properties samples were characterized using X-ray diffraction (XRD), scanning electron microscope (SEM). Open circuit potential (OCP) coefficient friction (COF) tests used examine performance. results...
Plasma Mo-Si-Ti coating including the (Ti, Mo)5Si3, MoSi2 and TiSi was prepared on γ-TiAl surface to improve wear resistance. The had 12-μm deposition layer 5-μm diffusion layer, as well gradual decrease of grain size from substrate coating, providing gradient structure high fracture toughness. Hardness (H), elasticity modulus (E), H/E H3/E2 values were 8.4 19.6 GPa, 167.2 251.8 0.050 0.078, 0.021 0.119 indicating that hardness, resistance plastic deformation load bearing capacity. During...
To improve the wear resistance of Ti6Al4V alloy, Ni-Cr alloy coatings with 40 at.%Ni were prepared on surface by double-glow plasma metallurgy technique. The friction and behaviour sliding against Si3N4 at room temperature 500 °C comparatively studied. results show that comprise a deposited layer, diffusion-modified layer heat-affected zone. deformed deposition plays an anti-friction effect as soft film. tribological diffusion is abrasive wear. alloying process significantly reduces...
A new surface strengthening process: Plasma chromizing was implemented on the metallic card clothing to improve its wear resistance based double glow plasma metallurgy technology. coating prepared in process, which consisted of a deposited layer and diffusion layer. The morphologies, microstructure, phase composition, hardness were analyzed detail. friction behaviors before after alloying comparatively under various sliding speeds at room temperature. results showed that: 1. dense...
In this study, a multilayered hard coating with tungsten matrix and transition layer was deposited on pure copper by double glow plasma surface alloying technology, which aimed to provide the superior binding force favorable matching of mechanical properties. The micro-hardness tester adopted measure cross-sectional hardness coatings. nanoindentation test used elasticity modulus Sliding wear tests under different conditions were performed W/Ta multilayer as well Cu substrate W coating....
