In this study, laser metal deposition (LMD) additive manufacturing was used to deposit the pure Inconel 625 alloy and TiC/Inconel composites with different starting sizes of TiC particles, respectively. The influence particle its original size on constitutional phases, microstructural features, mechanical properties LMD-processed parts studied. incorporation particles significantly changed prominent texture Ni–Cr matrix phase from (200) (100). bottom side each deposited track showed mostly...
The laser metal deposition (LMD) additive manufacturing process was applied to produce TiC/Inconel 625 composite parts. high-temperature oxidation performance of the LMD-processed parts and underlying physical/chemical mechanisms were systematically studied. incorporation TiC reinforcement in Inconel improved resistance parts, improvement function became more significant with increasing addition from 2.5 wt. % 5.0 %. mass gain after 100 h at 800 °C decreased 1.4130 mg/cm2 for 0.3233 625/5.0...
A heterogeneous catalyst CuO–CeO2 with a hollow structure was successfully synthesized by assembling CuO on the outer surface of CeO2 spheres through layer-by-layer deposition strategy. Further reduction under H2 atmosphere carried out to modify its state, resulting in sample r-CuO–CeO2. The catalysts were characterized X-ray diffraction, scanning electron microscopy (SEM), transmission (TEM), photoelectron spectroscopy (XPS), and Fourier transform-infrared (FT-IR). SEM TEM showed that had...
Cu–Al2O3 nanocomposite coatings were jet electrodeposited from an electrolyte containing Al2O3 nanoparticles and added thiourea. The effects of the thiourea concentration on surface morphologies, microstructures, growth structures, incorporated nanoparticle contents, mechanical performances composite examined. results revealed that adsorption increased 4.6 at% to 9.3 with addition thiourea, grain refinement 61 nm 33 was achieved. Thiourea additions in range 0–15 mg/L microhardness by 79%...
Abstract A 3 coupling reaction can be used to efficiently synthesize propargylamine, which is an important bioactive molecule intermediate, and copper sulfide (CuS) as its catalyst rarely reported. Herein, CuS with different morphologies including nanoflowers (NFS), nanorods (NR), nanoparticles (NP) were synthesized applied the reaction. The results show that NP has highest catalytic activity (99 % conversion) compared other CuS, also good group compatibility recyclability. Combining surface...
The present investigation concerned the fabrication of TiC (2.5 and 5 wt. %) reinforced nickel-based superalloy (NBS) composites by laser rapid forming (LRF) with a high power diode laser. Furthermore, evaluation microstructures wear resistance manufacturing specimens were researched. There four different species in LRF-processed pure NBS parts 2.5% TiC/NBS composites, including cellular grains, columnar crosslike dendrites. However, only grains could be observed 5% composite parts....
