Mechanical and tribological performance of (TiNbTaWMo)C high-entropy ceramics in a wide temperature range

Yuan Fang et al.

Summary: This study investigated the mechanical and tribological properties of (TiNbTaWMo)C high-entropy carbides over a wide temperature range, as well as their oxidation behavior. (TiNbTaWMo)C high-entropy carbides were successfully prepared from five kinds of carbide powders by spark plasma sintering at 2000°C. The results showed that the sintered (TiNbTaWMo)C high-entropy carbides had Vickers hardness of 21.31 GPa, bending strength of 477.15 MPa, and fracture toughness of 6.41 MPa m1/2. At room temperature, the friction coefficient was stable at 0.35, and the wear rate was as low as 3.39 x 10-7 mm3/Nm. The wear mechanisms at different temperatures and the oxidation behavior of (TiNbTaWMo)C at 600°C and 800°C were discussed based on microstructures and phase analysis of the worn surfaces.

Thermal cycle test performances of environmental barrier coatings of HfO2-SiO2/Yb2Si2O7 in the steam environment at 1475 °C

Zhenya Zhang et al.

Summary: The novel bi-layer environmental barrier coatings with HfO2-SiO2/Yb2Si2O7 structure were tested and evaluated in steam conditions. The 70HS/YbDS completely separated from the SiC substrate after 22 cycles, while the 50HS/YbDS and SiC did not separate, but cracks formed at the interface. Moreover, a thermally grown oxide (TGO) layer formed at the HfO2-SiO2/SiC interface, leading to the failure of EBCs.

A functionally graded coating from ZrN to Ti: Experimental characterization, erosion behavior and design concept

Jinwei Yi et al.

Summary: In functionally graded coatings (FGCs), the elemental composition or structure gradually changes as a function of depth, allowing for a gradual transition of properties. A sandwich-like ZrN/Ti FGC, fabricated using the double glow plasma alloying (DGPA) technique, demonstrated high adhesion and erosion resistance due to a transition layer derived from atom diffusion. The coexistence of metal and ceramic phases in the transition layer deflected radial crack propagation and increased plastic work consumption. Thermodynamic calculations showed that controlling the diffusion thickness of Zr over N can improve the phase content of ZrN and reduce the prevalence of unfavorable TiN and Ti2N phases.

Summary: In this study, silicon-hafnia feedstock was plasma sprayed to form Environmental Barrier Coating bond coat. The analysis showed that above 700 degrees C, HfSi2 oxidizes and HfO2 transforms into monoclinic phase, leading to non-linear expansion behavior. After 100 hours at 1300 degrees C, the coating cracked extensively due to the formation of SiO2 and HfSiO4 during cyclic oxidation.
