To improve the service life and wear resistance of agitator blade, AlCoCrMoVx (x = 0, 0.2, 0.4, 0.6, 0.8, 1.0 at.%) high entropy alloy (HEA) coatings were prepared on 904L-stainless-steel substrate by laser cladding, effect V content microstructure, corrosion behavior investigated. The HEA consist body-centered cubic (BCC) phase, needle-like σ irregular black AlN phase. As increases, phase gradually disappears. trend microhardness decreases firstly then increases. AlCoCrMoV1.0 coating has...
The agitator blade made by 904 L stainless steel was subjected to serious corrosion-wear due its low hardness in phosphoric acid reactors. In this aspect, various nano-TiC reinforced [Cr–Fe4Co4Ni4]Cr3 HEA composite coatings were designed using the cluster-plus-glue-atom model and fabricated on laser cladding. phase structure of composed FCC solid solution TiC phase. microstructure observation detected that tiny particles widely distributed along inter-dendrites matrix. Also, particle...
In the present work, an atoxic (TiZrNb)14SnMo refractory high-entropy alloy (RHEA) was successfully designed by a cluster-plus-glue-atom model for metallic-bioimplant application. Its bulk and coating were fabricated using vacuum arc-melting laser cladding techniques, respectively. The as-solidified RHEA consists of body-centered-cubic (bcc) structural dendrite rod-like hexagonal-close-packed (hcp)-(Sn, Zr) ordered phase. However, phase is fully restrained in as-clad coating. Moreover, with...
Since the traditional techniques for eliminating residual stress are complicated process and high production cost, we attempt to reduce generated in laser cladding a Fe-Mn-Si-Cr-Ni alloy coating through stress-induce solid phase transformation (SSPT). A 3D thermo-mechanical finite element model stress-induced transformations was developed research influences of SSPT on evolution during coating. In simulation calculation, distribution under two conditions (with without SSPT) were analyzed...
Electrochromic materials (ECMs) are capable of reversibly adjusting their transmittance or reflectance properties in response to changes the external biasing voltages. In this study, we enhanced electrochromic and electrochemical polyaniline (PANi) effectively through incorporation MXene Ti2CTx using an insitu composite strategy. This improvement observed can be attributed intermolecular forces between aniline group PANi terminal groups sheets. The presence hydrogen bonds monomers sheets was...
Modification of micro-nano structures on the surface medical implants using a femtosecond laser (FSL) can improve cell behavior, increase tissue and material bonding strength, promote preferred osseointegration. Nevertheless, FSL processed suffer from compromise between biocompatibility structural stability. Herein, Ti32.5Nb alloy cladding (LC) coating was initially created Ti6Al4V (TC4) substrate, followed by construction an armour-like structure with stability surface. The results show...
Two novel HEA compositions of [Nb¯-(FeCoNi)12]Cr3 (Nb¯= Nb, V) was designed using a high-entropy alloying strategy by analyzing traditional IN718 superalloy based on cluster-plus-glue-atom model. And their thin-wall-shaped bulks were prepared laser additive manufacturing, with an emphasis the effects V atoms to substitute for Nb microstructures and mechanical properties. Also, strengthening mechanism induced D019 precipitates as-aged V2Nb4 discussed. After contents inter-dendritic C14-Laves...
Natural blood vessels have a multi-layered, cell-specific oriented spatial structure, mimicking of this structure is promising way for vessel regeneration. In study, newly developed dual-oriented/bilayered small-diameter tubular scaffold was electrospun using mixture poly (ε-caprolactone) (PCL), (D, L-lactide-co-glycolide) (PLGA) and gelatin. The nanofiber orientations the bilayers were spatially perpendicular to each other, aiming at guiding orientation smooth muscle cells (SMCs)...
Developing high-performance high-entropy alloys (HEAs) fabricated by laser additive manufacturing (LAM) is the pursuit of metallic community. In present work, we designed a series [(Al6-xNbx)-(FeCoNi)12]Cr3 HEA compositions using alloying strategy based on cluster-plus-glue-atom model. And their thin-wall-sharped bulks were LAM and post-aging treatment. The effects cracking inhibition microstructure evolution tensile properties researched in detail. results show that as Nb substitutes for Al...
