The fabrication of zinc (Zn) parts devoid inherent defects through Powder Bed Fusion-Laser Beam (PBF-LB) remains a formidable challenge. This study focuses on the optimization process parameters and implementation tailored heat treatment to achieve high-performance PBF-LB fabricated (PBF-LBed) pure Zn bulk scaffolds. Microstructural analysis, residual stress assessment, mechanical property testing, electrochemical experiments, immersion tests, in vitro vivo evaluations were conducted....
Purpose Stainless-clad bimetallic steels (SCBS) are widely investigated in some extremely environmental applications areas, such as polar sailing area and tropical oil gas platforms because of their excellent anticorrosion performance relatively lower production costs. However, the properties SCBS, including mechanical strength, weldability behavior, have a direct relation with manufacturing process can affect practical applications. This paper aims to review application requirements SCBS...
<title>Abstract</title> The part with lattice structures generally consists of a framework and structures. Since its slices contain the large-area contours some small discrete structures, use scanning strategy recommended by SLM machine supplier may result in material shape defects, especially case Therefore, this article proposes rectangular ring area-partition (RRAP) combined 67<sup>o</sup>-interval rotating for parallel line (PL) In order to study influence on produced samples from...
In this study, conventional and nanostructured Al2O3-13 wt% TiO2 coatings were fabricated by plasma spraying. The microstructural characteristics, bonding strength solid particle erosion behaviours of the two types compared. Results indicated that traditional coating has a typical laminated structure. exhibited bimodal microstructure consisting fully melted regions partially regions. wear resistance considerably better than those one due to compact nanoparticles Erosion failure analysis...
AlCoCrFeNi2.1/WC eutectic high-entropy alloy composite coatings were prepared on a 316L stainless steel substrate via the laser cladding method. The effects of WC content phase composition, microstructure, and mechanical properties investigated. results revealed that laser-clad coating mainly consisted FCC BCC phases. As increased from 0 wt.% to 30% wt.%, Cr7C3 Cr21W2C6 phases gradually precipitated coating. Consequently, microhardness 318.6 572.3 HV1.0. strengthening mechanism comprised...
Abstract Pure titanium (Ti) which had been processed by high energy ball milling, graphite and Ni60A self-melting alloy composite powder were used as the cladding materials. A test on in situ synthesized graded TiC particulate reinforced Ni-based coating was carried out after presetting of 42CrMo structured steel base surface. Morphologies, tissue structures microhardness values samples investigated an optical microscope (OM), scanning electron (SEM) tester. Results show that synthesis...
Abstract Al 2 O 3 -13wt.%TiO composite ceramic coatings were prepared by plasma spraying and laser remelting. Morphology, microstructure phase composition analyzed scanning electron microscope (SEM) X-ray diffractometer (XRD). Meanwhile, effects of remelting on thermal shock resistance plasma-sprayed investigated the failure mechanism discussed. Results demonstrate that after remelting, particles coating are refined lamellar structure disappears, thus increasing density getting a basically...
Abstract With characteristics of high cladding efficiency, small grain size and low porosity, follow-up feeding pulse current assisted laser can realize online self-healing cracks on the layer get a crack-free layer. It is very promising new technology. In this study, effects parameters (laser power, scanning speed, powder feed rate, current, frequency width) dilution rate coating were discussed through six-factor three-level orthogonal experimental design method. Results demonstrated that...
Titanium alloy, particularly Ti6Al4V, is commonly used for constructing the framework of implant-supported fixed complete dentures (IFCDs) but exhibits poor specific strength and impact toughness. Three-periodic minimal surface (TPMS) porous structures have advantages high strength, lightweight, shock energy absorption. Therefore, functionally graded TPMS structure was adopted to design IFCDs in this study. Nine types TPMS-based lattice with radial gradient variations were designed. Finite...
