Article Synopsis
- Aluminum matrix composites reinforced with carbon fibers or diamond particles were created using a powder metallurgy process for thermal management applications.
- These composites do not react chemically due to an alumina layer on aluminum powder particles, allowing for a stable system.
- The addition of Al-Si alloys during the fabrication process improved the density and thermal properties of the composites, resulting in better thermal conductivity and thermal expansion characteristics than those without the alloys.
The defective fluorite-related YNbO host lattice was doped with Eu ions to understand the influence of spark plasma sintering (SPS) process on this host lattice. The intrinsic disorder due to the occurrence of oxygen vacancies results in amorphous-type responses of the luminescent cations, and the spectral distribution varies as a function of the niobium content. Two spectral fingerprints of europium emissions were clearly enhanced.

- The presence of cobalt in cemented tungsten carbide (WC-Co) substrates negatively impacts the quality of diamond films by promoting nondiamond carbon formation, which decreases adhesion and overall diamond quality.
- This study explored three different pretreatment methods for WC-Co substrates—chemical etching, laser etching, and laser etching followed by acid treatment—to improve diamond film deposition.
- Laser etching was found to enhance surface roughness and relieve stress at the interface between the substrate and diamond film, with diamond quality and residual stress assessed using Raman spectroscopy.
