Selective laser melting (SLM) and direct metal deposition (LMD) have shown promise in advanced manufacturing. However, limited research fabricating the same material using these methods, particularly regarding mechanical properties residual stresses. In this study, 24CrNiMo blocks were prepared SLM LMD subjected to stress relief annealing (SR). The microstructure, stresses, investigated SEM, XRD, EBSD, testing, μ-X360n analysis. results showed that microstructure of both composed α-Fe. due...
This study reported the fabrication of Ni50 and Ni50-WC coatings while employing laser cladding manufacture (LCM) technique. The surface cross-sectional morphologies, microhardness, phase structure, corrosion, wear resistances were measured using a scanning electron microscope (SEM), stereoscopic microscope, X-ray diffractometer (XRD), microhardness tester, electrochemical workstation, friction tester. These results illustrated emergence γ-(Ni, Fe), WC, W2C, M23C6, M7C3, Ni3Fe phases in...
Doxycycline (DOX) is extensively utilized as a broad-spectrum antibiotic in animals and aquaculture. However, excessive residues of DOX can endanger human health ecosystems, adversely affecting sustainable development. A novel ratiometric fluorescent probe was designed for specific monitoring based on boron- nitrogen-codoped carbon quantum dots encapsulated metal–organic frameworks coupled with molecularly imprinted polymers (B,N-CQDs/ZIF-8@MIP). In the existence DOX, blue fluorescence...
Efficient and accurate semantic segmentation is the key technique for automatic remote sensing image analysis. While there have been many methods based on traditional hand-craft feature extractors, it still challenging to process high-resolution large-scale images. In this work, a novel patch-wise method with new training strategy fully convolutional networks presented segment common land resources. First, handle image, images are split as local patches then network built. Second, data...
Smart railway maintenance is crucial to the safety and efficiency of operations. Successful deployment technologies such as condition-based monitoring predictive will enable companies conduct proactive before defects failures take place improve operation efficiency. In this paper, we first propose develop a classification-based method detect rail localized surface collapse, end batter, or components—such joints, turning points, crossings, etc.—by using acceleration data. order performance...
A design strategy is presented for the development of a laser-deposited Stellite 6 coating with high ductility and low thermal fatigue crack propagation rate. The involved adding titanium to modify carbide morphology, accompanied by an increase in nickel content stabilize γ-Co phase matrix. molar ratios carbon coatings were 0.5, 1.0, 1.5, 2.0. amount added titanium-modified was 10 20 wt%. net-like M23C6 eutectic carbides transformed isolated TiC particles increasing ratio carbon. Adding...
G20Mn5QT steel has excellent mechanical properties and is widely used in key components of rail vehicles. However, during the operation high-speed vehicles, wear tear will inevitably occur. In this paper, laser cladding technology was selected to successfully prepare 316L stainless coating. The optimum processing parameters were obtained with a power 2300 W, scanning speed 500 mm/min, powder feeding 14 g/min. microstructure coating mainly composed planar crystals, cellular columnar equiaxed...
