Ti–Nb alloys have the advantages of non-toxicity, low elastic modulus, high strength, and good biocompatibility. However, effect Nb content on its passivation behavior in Hank's solution still needs to be investigated. This work investigated microstructure, hardness, corrosion Ti-xNb (x = 5, 15, 25 wt%) alloys. The β phase gradually increases associated with increasing alloys, resulting dispersion strengthening Moreover, increased content, samples show higher open circuit potential, lower...
Remanufacturing worn parts by the laser cladding process has wide prospect. To repair camshafts, T15 alloy steel coatings with different content of Cr were fabricated preset-powder (PPLC). The effect (3, 6, 9 and 12 wt%) on microstructure wear resistance was investigated from aspects solution element, grain size phase composition. results indicate that is composed martensite, retained austenite (RA) eutectic boron-carbides. martensite increases first then decreases, RA decreases...
This article focuses on investigating the effect of printing direction mechanical properties Cu–10Sn alloys prepared by laser powder bed fusion (LPBF) technology. Specimens with different forming angles (0°, 15°, 30°, 45°, 60°, 75°, and 90°) were fabricated using LPBF technology, their systematically tested. During testing process, we used an Instron 5985 electronic universal material machine to accurately evaluate at a constant strain rate 10−3/s. The experimental results showed that...
In this experiment, Cu2O/Ag co-deposition TiO2 nanotube array (Cu2O-Ag-TNT) film was prepared on pure Ti substrate with the method of combining anodic oxidation and electrodeposition by pulse-reversing voltage power supply in electrolyte NH4F, ethylene glycol, CuNO3 · 3H2O AgNO3. The morphology, phase, chemical composition, photocatalytic property mechanism were studied means scanning electron microscopy, energy dispersive x-ray spectroscopy, diffraction, photoelectron transmission UV–vis...
ZnO doped TiO₂ nanotube arrays (ZnO-TNTs) with an average diameter of 60~80 nm and length 2~4 μm were prepared on the Ti substrate by a one-step anodizing method using NH₄F/ethylene glycol as electrolyte. The phase structure, morphology, chemical composition, photocatalytic property mechanism TNTs studied scanning electron microscopy, energy dispersive X-ray spectroscopy, diffraction, transmission UV-vis diffuse reflectance spectra, photoluminescence degradation methylene blue under visible...
ZnO/Ag multi-phase composited TiO2 nanotube arrays (TiO2 TNAs) films were prepared on pure Ti substrate through one-step anodizing method using double pulse plating power supply. The deposition amount of Ag and ZnO adjusted by changing the concentration Zn(NO3)2·6H2O AgNO3 reverse voltage. results showed that deposited in wall NTAs dispersedly; sedimentary phase dispersed are two forms NTAs. bandgap narrowed 0.33 eV, recombination rate photo-generated electron-hole pairs also decreased...
Based on the fretting wear failure of key parts short stress line rolling mill, selective laser melting was chosen to repair parts. The effect scanning rate microstructure, hardness and resistance cladding layer studied. results show that microstructure is mainly lamellar martensite with a little retained austenite carbide. increases increase decrease energy density. maximum about 950 HV<sub>0.2</sub>. friction coefficient varies different rate. firstly then decreases sample 6 mm/s smallest,...
