To solve the lack of wear resistance titanium alloys for use in biological applications, various prepared coatings on are often used as wear-resistant materials. In this paper, TiC bioinert were fabricated Ti6Al4V by laser cladding using mixed and ZrO2 powders basic pre-placed A certain amount CeO2 powder was also added to further improve properties coatings. The effects additive phase constituents, microstructures researched detail. Although effect constituents slight, it had a significant...
Ti-based ceramic coatings on Ti6Al4V substrates were successfully prepared through a laser cladding process using pre-placed starting materials of TiCN + SiO2 mixed powder without or with adding 3 wt % CeO2 nanoparticles additive, aiming at improving the wear resistance alloy for biological applications. The effects additive microstructure, microhardness, and performance analyzed in detail. observations showed that main compositions coating TiN phase. Compared to CeO2, modified led more...
For magnesium (Mg) matrix composites (MMCs), trade-off between strength and plasticity has long been an issue of puzzle. In this work, hot-press sintering hot extrusion are used to prepare Ti particles (Tip) reinforced AZ31 (Tip/AZ31) composites. The strength, plasticity, wear resistance Tip/AZ31 improved simultaneously. refine the grains accelerate precipitation Mg17Al12 in Mg matrix. best tensile properties achieved 6 wt%Tip/AZ31 composite, with ultimate 290 MPa, elongation 15.5 %, rate...
The persistent challenge of achieving cost-effective total phosphorus (TP) removal in wastewater treatment necessitates innovative coagulant development. While polyaluminum chloride (PAC) demonstrates efficacy eliminating nitrogen (TN), ammonia (NH4+-N), suspended solids (SSs), and pH stabilization, its limitations attaining economical TP remain unresolved. This study introduces a novel FeSO4-Al2(SO4)3 composite to address PAC’s shortcomings through systematic formulation optimization....
The effective recovery of valuable materials from spent LiFePO4 batteries is crucial for resource sustainability and environmental protection. This study investigates the phosphorus iron slag waste batteries, focusing on dissolution impurity removal processes to produce battery-grade phosphate. Using high-temperature-activated dissolution, followed by precipitation/dissolution removal, we optimize conditions ensure high rates (up 98.8% FePO4 under optimized conditions) product purity. Our...
Using Ni60 alloy, C, TiN and Mo mixed powders as the precursor materials, in situ synthesized Ti(C,N) particles reinforcing Ni-based composite coatings are produced on Ti6Al4V alloys by laser cladding. Phase constituents, microstructures wear properties of with 0 wt % Mo, 4 8 additions studied comparatively. Results indicate that is formed metallurgical reaction, (Ti,Mo)(C,N) rim phase surrounding ceramic particle addition increase content beneficial to improve cladding coatings. Because...
To improve the wear resistance of titanium alloy parts used in engineering applications, in-situ formed Ti(C,N) particles reinforcing Ni-based composite coatings are fabricated on Ti6Al4V alloys by laser cladding technique using Ni60, C, TiN, and small amounts CeO2 nanoparticles mixed powders as pre-placed materials.

AbstractAbstractConventional surface grinding can be divided into up and down according to rotation direction of spindle. Nevertheless, the effects differences ultrasonic vibration on two machining methods have been less reported. The influence amplitude cutting force, roughness topography were investigated in this paper by conducting tangential radial assisted down/up comparison experiments SiC. results showed that force was than conventional grinding, while greater grinding. forces both...
In this paper, constrained nonsmooth resource allocation problems (RAPs) of autonomous agents are investigated. All subject to inequality network constraints and local constraints, each agent has a private payoff function in our problem. Furthermore, contrast the well-known RAPs, all have second-order linear/nonlinear (SOL/SON) dynamics, which means that there is no way directly control actions To best knowledge, results on RAPs SOL/SON agents, let alone involving constraints. Existing...
