Abstract:
AbstractA hard composite coating was fabricated by laser alloying of the Co-Fe-Al+B4C-Si3N4 mixed powders on TA15 (Ti-6Al-2Zr-1Mo-1V) titanium alloy in an open system. The composite coating mainly consisted of γ-Co, TiB2, TiB, TiC0.3N0.7, SiC, Ti3Al, FeAl, and Co-Ti intermetallics. The TEM diffraction pattern results indicated that the orientation relationship between TiB2 and TiC0.3N0.7 was (1-20)TiB2//(2-20)TiC0.3N0.7 in such a coating. Furthermore, during the alloying process, a number of Mo and Zr entered into the molten pool from the substrate due to the dilution effect, which refined the

The technology of the TiB2/TiB cladding layer addresses the issue of the insufficient wear resistance of cup-shaped parts composed of titanium alloy materials. In order to eliminate the cracking problem of laser cladding TiB2/Ti-based alloy, 30%TiB2/Ti-based alloy gradient coating was prepared on the surface of titanium alloy by laser cladding in this study. The results revealed that the microstructure of the matrix and the cladding layer is metallurgically bonded.

The composite cladding layer was produced using different powder mixtures: 85wt.% TiB2-15wt.% Ti, 75wt.% TiB2-25wt.% Ti, and 65wt.% TiB2 -35wt.% Ti. During cladding, the GTA process currents were used in the range of 70A to 90 A with 10A interval differences and the scan speed in the range of 1.1 mm/sec to 1.9 mm/sec with 0.4 mm/sec interval differences. All samples were investigated

AbstractThe aim of achieving integration of lightweight, high strength, high‐temperature resistant, and satisfactory electromagnetic (EM) wave absorption was successfully accomplished in the present study by synthesizing TiC–TiB2 fibers reinforced Si3N4 composites, which were pressureless sintered at 1650°C for 2 h. The preparation of TiC–TiB2 fibers was conducted through a chloride‐assisted carbothermic method. This work focused on investigating the effects of incorporating TiC–TiB2 fibers on the mechanical properties and EM wave absorption characteristics of the composites. The 30 wt% TiC–Ti

Abstract:
In this study, the microstructural and mechanical properties of Al-Si3N4/TiB2 hybrid reinforced composites are examined. The aim is to investigate the impact of a novel combination of reinforcements (Si3N4/TiB2) on the mechanical behavior of hybrid metal matrix composites (HMMCs). The composites are produced by adding a fixed amount of Si3N4 (4 wt.%) and 2, 4, and 6 wt.% of TiB2, respectively, into molten AA7075 aluminum alloy using a liquid state stir casting process. The physical and mechanical properties of fabricated HMMCs are determined through the measurement of density, porosity, tensil

AbstractIn this study, the Si3N4–TiB2/SiCN–B4C laminated the ceramic tool integrating force measurement function with piezoresistive effect was fabricated. The influence of thickness ratio on the residual thermal stress distribution, the mechanical properties, microstructure and piezoresistivity of the laminated ceramic were investigated. The turning experiment was carried out. The results indicate that the microstructure of laminated ceramic was similar with different thickness ratio. However, the thickness ratio can influence the mechanical properties of laminated ceramics by residual therma

AbstractTo date, the thermal and electrical properties of three‐phase ceramics containing a boride phase, silicon carbide, and boron carbide have not been studied in detail. Further, the effect of the source of the boride powder has also not been investigated. This study produced three‐phase ceramics containing titanium diboride, silicon carbide, and boron carbide using three different TiB2 sources: commercial powder, TiB2 synthesized by boro/carbothermal reduction, or (Ti,Cr)B2 synthesized by boro/carbothermal reduction to address the effect of the TiB2 source.

AbstractHigh‐activity TiB2 submicron powders were synthesized via microwave‐assisted carbothermal reduction, and their oxidation behavior at 550°C–1000°C for 0.5–1.5 h in air atmosphere was carried out by the isothermal oxidation test. The phase composition and microstructure evolution of the oxidation products were performed by X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). It was established that TiB2 submicron powders had been significantly oxidized at 550°C, and the oxidation products were TiO2 and B2O3. Hexagonal plate‐like TiB2 gr

Abstract:
The utilization of TiB2 particle reinforcement in aluminium matrix composites, particularly with Al6063, has been explored in this study for its resilience to mechanical erosion, low oxidation rate, and excellent heat conductivity. The composite was produced using stir casting with 9 wt% TiB2. The investigation focuses on wear behaviour, examining three key process parameters such as load, sliding speed, and covering sliding distance across four settings to identify the optimal combination for achieving a favourable wear rate.
