In this study, (CoCrNi)87M8B4C1(M: V/Nb) composite coatings were fabricated by laser cladding. The Nb-containing coating showed a better wear resistance than the one containing V. Both can form highly stable passive films in corrosive environments due to coherent phase interfaces and high solid solubility of metal elements M23C6. film exhibits higher impedance as Nb increase internal electric field strength within film, enhance thickness, lower potential difference at film/solution...
The immune system of a host functions critically in shaping the composition microbiota, and some microbes are involved regulating endocrine development. However, whether acts on development by microbiota remains unclear, few molecular players or this process have been identified. In current study, we found that RNA interference C-type lectin (HaCTL3) cotton bollworm Helicoverpa armigera suppresses ecdysone juvenile hormone signaling, thus reducing larval body size delaying pupation....
Al–Li alloy 2A97 is one promising that could be widely used in the aerospace field to achieve weight lighting. Due addition of lithium element, its anticorrosion attracts widespread interest. In this study, milled surfaces and ground‐polished are characterized compared from three aspects surface integrity, namely roughness, residual stresses, work‐hardening. After potentiodynamic polarization measurements were conducted on machined samples with different 3.5 wt% sodium chloride solution,...
This paper aims at comparing the surface integrity and fatigue performance of hardened AISI D2 steel ball-end milled with different milling speeds. Results show that speed has a significant effect on topography, roughness, microhardness residual stress. The life for samples hard was raised least 83% compared polished samples. is ascribed to high compressive stress enhanced induced by process. maximum difference in about 12.2% spindle N ranging from 3000 r/min 8000 r/min. Samples low or have...
To provide guidance for the tool materials selection in machining of high-strength steels, this article outlines application fuzzy comprehensive evaluation method cutting performance cemented carbide tools, ceramic and cermet tools. The results indicate that cermets with best are chosen as optimum steels. Moreover, severe adhesion wear characteristics tools detrimental to surface quality workpieces. obvious crater furrow-like scratches caused mainly by abrasive wear, well adhesive can...
This study focuses on systematically revealing how cutting parameters influence the surface integrity of ball-end hard milled AISI D2 steel and proposing optimization scheme from integrity, wear resistance fatigue perspective based response methodology respectively. Results can be summarized into three aspects. Firstly, radial depth cut with percent contribution ratio (PCR) 62.05% has a decisive roughness, followed by spindle speed 13.25% feed per tooth 6.63%. The work hardening degree was...
5G IoT communications have some new requirements on the whole system design, e.g., low cost, power consumption, long distance coverage and massive connection. To fulfill all these requirements, a narrow-band SCMA scheme is proposed. Narrow band pulse shaping employed, so that can be expanded with low-cost low-power devices. Two types of waveforms are provided, both which use to enlarge number supported Simulation results show that, comparing existing narrow techniques, support more dense...
Smart power grid is a two-way interconnected network in which information plays fundamental role the process of energy transmission and distribution. The smart based on combining ICT with processing capabilities computers electrical systems to increase communication between users. However, grids are exposed variety malicious cyber-attacks that can lead destruction basic infrastructure disrupt Meanwhile, by authenticating authenticated users, cyber-security be created grid. One main...
As an important artificial implant material, the corrosion resistance of NiTi shape memory alloy is closely related to machined surface quality. In this paper, multiple analysis methods concerning potentiodynamic polarization, impedance spectrum and morphology are used analyze alloy. The polarization test results show that conductivity current density electrochemical polishing decrease, potential increase compared with milling. After polishing, roughness milling sample decreased, austenite...
