Electric field assisted sintering of gadolinium-doped ceria

open access: yes, 2020
10 mol% Gadolinium-dotiertes Ceroxid (GDC10) ist ein Werkstoff von hoher technologischer Relevanz für eine potentielle Anwendung in elektrochemischen Zellen, Sauerstofftransportmembranen und Katalysatoren. Ein wesentlicher Nachteil ist jedoch, dass die Verarbeitung von GDC10 hohe Sintertemperaturen (1300°C-1600°C) mit Verweilzeiten von mehreren Stunden

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

open access: yesAdvanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Active Corrosion Protection of Sintered AA7075 Aluminum Alloy via Mn Powder Addition

open access: yesAdvanced Engineering Materials, EarlyView.
AA7075 containing Mn‐rich particles is fabricated via spark plasma sintering using AA7075 and Mn powders. Corrosion resistance is evaluated through dip‐and‐dry tests using 0.1 M NaCl (pH 6.0), and mass loss decreases with increasing Mn addition. Mn‐rich particles function as a source of Mn ions, and formation of Mn‐accumulation films on Cu‐containing ...
