Fracture behaviour of ceramic–metallic glass gradient transition coating

Influence of ceramic substrate porosity and glass phase content on the microstructure and mechanical properties of metallized ceramics via an activated Mo-Mn method

“…The present of Al and Mo in the two adjacent phases is clearly seen in the elemental maps. This observation supports a previous conclusion, that a continuous Mo framework is important for a good connectivity between the ceramics and the Cu alloy bar [41]. The metallized layer near the Al2O3-metal interface is enriched with Mn (Fig.…”

The thermo‐mechanical properties and ferroelastic phase transition of RENbO4(RE = Y, La, Nd, Sm, Gd, Dy, Yb) ceramics

“…Metal components inside aero‐engines and gas turbines need to operate in high temperature, high pressure, and corrosive environments for a long time, so an effective measure to protect these metal components is necessary. The most widely used method is to deposit thermal barrier coatings (TBCs) materials with high melting point and low thermal conductivity on the surface of metal components, which can mitigate the impact and corrosion of the high temperature gas . Currently, the state‐of‐the‐art TBCs materials are 7‐8YSZ (7‐8.wt% yttria‐stabilized zirconia) with low thermal conductivity (2‐3 W [m k] −1 ) and high thermal expansion coefficients (10‐11 × 10 −6 k −1 ) .…”

[1][2][3][4][5] Currently, the state-of-the-art TBCs materials are 7-8YSZ (7-8.wt% yttria-stabilized zirconia) with low thermal conductivity (2-3 W [m k] −1 ) and high thermal expansion coefficients (10-11 × 10 −6 k −1 ). 6 Besides, YSZ possesses excellent high-temperature toughness compared to other oxide ceramics, which is related to the ferroelastic toughening mechanism of the tetragonal-prime (t′) phase.…”
