The purpose of the present study was to learn morphological, structural, ferroelectric, dielectric, electromechanical, magnetoelectric, and magnetic properties, DC conductivity BaTiO3-Ni0.64Zn0.36Fe2O4 (BT-F) multiferroic composites compacted via free sintering method. influence ferrite content in ceramic composite materials on functional properties is investigated discussed. X-ray diffraction studies confirmed presence two main phases composite, with strong reflections originating from...
Biodegradable materials, especially Magnesium (Mg) and its alloys, are preferred for bone implants due to their compatibility with host tissue biomechanical support. However, rapid corrosion vulnerability structural failure, compounded by infections from antibiotic-resistant bacteria, pose significant challenges. Addressing these issues, we developed silicate-based composite coatings varying CuO concentrations (1, 5, 7 wt%) on Mg using plasma electrolytic oxidation (PEO). This study...
Herein, a study of the plasma electrolytic oxidation (PEO) niobium in an anodising bath composed potassium silicate (K2SiO3) and hydroxide (KOH) is reported. The effects K2SiO3 concentration process voltage on characteristics obtained oxide layers were assessed. Compact, barrier-type when did not exceed breakdown potential layer. When this threshold was breached, morphology layer changed markedly, which typical PEO. A significant amount silicon, form amorphous silica, incorporated into...
The paper introduces spatially stable Ni-supported bimetallic catalysts for CO2 methanation. are a combination of sintered nickel mesh or wool fibers and nanometal particles, such as Au, Pd, Re, Ru. preparation involves the forming sintering into shape then impregnating them with metal nanoparticles generated by silica matrix digestion method. This procedure can be scaled up commercial use. catalyst candidates were analyzed using SEM, XRD, EDXRF tested in fixed-bed flow reactor. best results...
In this paper, a ribbon of binary Ni–Nb amorphous alloy was prepared by the melt spinning technique. Glass transition and crystallization phenomenon were investigated differential scanning calorimetry. Thermal properties upon heating cooling analysed DTA at heating/cooling rate 0.5 K s−1 under purified argon atmosphere. The thermal stability studied using an X-ray diffractometer equipped with in situ system. structure fracture morphology ribbons examined diffraction electron microscopy methods.
The main aim of this study was the fabrication functionally graded materials for biomedical applications. Samples with gradient porosities were prepared by a two-stage powder metallurgy method. internal and external zones both samples composed different phases pore structures. phase compositions, microstructures, porosities, microhardness sintered analysed. results revealed successful method, transition zone (formed diffusion) between found to be permanent. Rietveld refinement analysis...
In this work, three composite materials based on Terfenol-D and PZT-type material were obtained with a classic sintering method using combination of 0-3 phases, where the ferroelectric phase was doped PZT (P) magnetic (T). The percentage P T components in composites variable, i.e., 90% P/10% (P90-T10), 70% P/30% (P70-T30), 50% P/50% (P50-T50). Structural, microstructure, dielectric, properties DC electric conductivity multiferroic investigated. Chemical composition analyses X-ray studies...
Three alloys differing in their nominal chemical composition (Ni50Ti50, Ni51Ti49, and Ni52Ti48) were produced the form of powders using high-energy ball milling. Their microstructure, morphology, structure, phase studied X-ray diffraction technique, scanning, transmission electron microscopy. For detailed structural analysis, Rietveld method was used. The results show that each consists three fractions: fine, medium, thick. fractions varied particle/agglomerate size from 200 nm to 800 μm....
