Summary: A new composite coating has been developed to protect carbon/carbon composites from oxidation. The best oxidation resistance is achieved with a 20% ZO content in the coating. The growth of bubbles during oxidation is caused by the reaction between SiC and oxygen, and the difference in thermal expansion coefficients may induce cracks in the coating during cooling.

Summary: Polysiloxane (PSO) was used as the matrix and SiC-ZrB2 powder as the filler to repair prefabricated defects on the SiC-ZrB2/SiC coating of carbon/carbon (C/C) composites. Different treatment processes were applied to investigate their effects on the repair agents' chemical composition, microstructure, and oxidation resistance behavior. Both processes resulted in pyrolysis and the generation of SiOC ceramics, which were well combined with the original coating. The repaired coatings showed improved thermal stability and oxidation resistance compared to the unrepaired coating, providing an effective and simple approach for repairing damaged coatings in high-temperature applications.

Summary: A HfB2-SiC skeleton was designed using hollow SiO2 microspheres as sacrificial templates on SiC-coated C/C composites. The skeleton was densified by SiC via chemical vapor infiltration to fabricate a dense SiC-HfB2 oxidation protective coating. The uniform distribution of HfB2 in the coating enhanced its effectiveness in covering cracks in the SiC inner coating. Hf-oxides contributed to the stability and inhibition of SiO2 volatilization in the compound glass layer. The coating exhibited excellent oxidation protection for C/C composites under high temperatures.

Summary: Carbon fiber reinforced carbon composites (C/Cs) are promising high-temperature materials, but they are prone to destructive oxidation at elevated temperatures. Matrix modification and coating technologies are not sufficient due to brittleness of ceramics and other inherent issues. Micro/nano multiscale reinforcing strategies have been developed in the past two decades to fabricate C/Cs with high strength and excellent high-temperature stability.

Summary: In this study, an in-situ SiC-HfB2-Si ternary coating was deposited on C/C composites using slurry panting and gaseous Si infiltration composite method to enhance oxidation and ablation resistance at temperatures above 1773K. The coating exhibited effective protection against oxidation due to the compact mosaic structure filled with HfB2-rich Si-based multiphase and the dense Hf-Si-O oxide layer. Additionally, the coating showed good ablation resistance with low linear and mass ablation rates, attributed to the stable oxide scale with high viscosity.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
