A novel high-entropy material as well as ultra-high temperature ceramic (Ta 0.2 Hf 0.2 Zr 0.2
Ti 0.2 Nb 0.2) C 0.8 N 0.2 was synthesized from ten kinds of transition metal carbides and …

For high-temperature applications, poor oxidation performance of Ta–Hf–C ternary ceramics
is an important life-limiting factor. In this work, the oxidation mechanisms of various …

To develop an ultra-high temperature resistant coating for niobium alloy, a new type of 10%
ZrB 2+ 5% YSZ-modified Si-Mo-18% W coating with a boride diffusion barrier was prepared …

Abstract MoSi 2-NbSi 2 coating and Ce-modified MoSi 2-NbSi 2 coating were prepared on
Nb-alloy through a new two-step process, including molybdenum slurry spraying and halide …

High-temperature elemental inter-diffusion is an important cause of failure for high-
temperature antioxidant coatings on tantalum substrate, yet little research has been reported …

Abstract A novel MoSi 2–Al 2 O 3 composite coating was prepared on Mo-based TZM alloy
by slurry sintering method. The oxidation behavior of the coating was evaluated at 1600° C …

In order to solve the challenge of recyclability of tantalum substrates in high temperature
oxidation environments, a novel MoSi 2-WSi 2-HfSi 2-TiSi 2 composite ceramic coating …

To improve the oxidation resistance of a Mo substrate at high temperatures, MoSi 2–MoB
double layers were prepared on the surface of the substrate using a two-step pack …

MoSi 2 coatings with different mullite additions (0, 10 wt%, and 30 wt%) were prepared on
siliconized Nb alloys and oxidation behaviors of the modified coatings were comparatively …

Abstract A novel Mo-Si-B-TiB 2 composite coating was prepared on Nb-Si based ultrahigh
temperature alloy by slurry sintering. The effects of TiB 2 contents (1, 3, 5 and 10 wt%) on the …
