High-Pressure Sensors Based on Laser-Manufactured Sintered Silicon Carbide [PDF]
Applied Sciences, 2020 In this work Sintered Silicon Carbide (S-SiC) samples have been used to fabricate fiber-optic-coupled pressure sensors. The sensor structure reproduces a low-finesse Fabry–Perot (FP) interferometer. Laser manufacturing of cylindrical S-SiC samples was performed to define the thin membrane geometry of sensors.

Spark plasma sintered carbon electrodes for electrical double layer capacitor applications [PDF]
, 2011 The spark plasma sintering (SPS) is an emerging process for shaping any type of materials (metals, ceramic, polymers and their composites). The advantage of such a process is to prepare densified ceramic materials in a very short time, while keeping the ...

Advanced Engineering Materials, EarlyView.Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Porous Titanium for Biomedical Applications: Evaluation of the Conventional Powder Metallurgy Frontier and Space-Holder Technique [PDF]
, 2019 Titanium and its alloys are reference materials in biomedical applications because of their desirable properties. However, one of the most important concerns in long-term prostheses is bone resorption as a result of the stress-shielding phenomena ...

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...
