This study systematically evaluates the tensile strength, impact and microhardness of 316L stainless steel fabricated using selective laser melting (SLM) at varying scanning speeds. The results are also compared with those traditionally forged steel. experimental findings indicate that SLM samples exhibit superior ultimate yield due to finer microstructure produced by rapid cooling rates inherent in processes. However, increased porosity leads a reduced elongation failure toughness Among...
Abstract The frictional performance of materials used in face seals is critical to the sealing performance. Silicon carbide commonly hard rings because its abrasion resistance, corrosion and thermal shock resistance. In this study, silicon carbide, including graphite-added under water lubrication-absent conditions was studied by using a Falex-1506 tribotester different working parameters. addition, morphology worn surfaces observed scanning electron microscopy damage characterized understand...
Purpose – It is aiming at finding tribology performance laws and mechanism of sintering materials, including new which are popular or potential materials mechanical seals working under water condition with different parameters, involving load sliding speed. Design/methodology/approach Falex-1506 tribo-machine has been used. The upper sample rotated against the stationary below. They all rings. samples WNV2, sintered pressureless bonded; CHV1, graphite-added PLSiC; R, reaction R2, RBSiC,...
Abstract The microspheres prepared by the microfluidic‐assisted internal gelation process are still challenging to reach millimeter size due large gravity. gravity would affect sphericity and uniformity of microspheres. improved is designed optimized produce large‐sized monodisperse ceramic with good sphericity. movement mechanism millimeter‐sized sol droplets gel in microchannel summarized state dispersed phase entering measuring cylinder controlled. friction between tubing wall reduced as...
The nontrivial degeneracies in non-Hermitian systems, exceptional points (EPs), have attracted extensive attention due to intriguing phenomena. Compared with commonly observed second-order EPs, high-order EPs show rich physics their extended dimension and parameter space, ranging from the coalescence of into higher order potential applications topological properties. However, these features also pose challenges controlling multiple coherent dissipative elements a scaled system. Here we...
As a single-center retrospective study, we analyzed the results of rotavirus and human adenovirus antigens in stool samples with colloidal gold immunochromatography method children acute gastroenteritis under age five who were treated our hospital from 2019 to 2022. After excluding nonconforming cases duplicate cases, 2 896 included, which 559 detected at least one viral antigen. According test results, they divided into RV positive group, HAdV group & double group. The gender, age, seasonal...
Abstract Nanocrystalline zirconium nitride (ZrN) powder was prepared by using internal gelation combined with carbothermic nitridation. As a carbon source, fructose added in the process to facilitate homogeneous dispersion. Fructose decomposed and ultrafine generated in-situ at high temperature. The acted as reducing agent remove oxygen atoms nitridation process. effects of on phase composition, morphology, grain size specific surface area were analysed. led peculiar morphology particles....
