We report the synthesis of SiC/Si3N4 coatings on carbon/carbon composites via pack cementation and heat treatment with nitrogen gas, the latter of which improves the coating wear resistance. X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) are used to analyse the microstructure, surface morphology
Crack healing behavior of SiC ceramics with large crack width has been studied as a function of coating and heat treatment. The SiO2 colloid coating was carried out on two types: hydrostatic pressure coating and roll coating. The crack healing was one hour at 1173 K in air. The crack part formed SiO2 oxides until the critical times by a hydrostatic pressure
The TaC coating effect was further validated by SiC crystal shape and quality through a series of growth experiments. As our study revealed, TaC coating can act as a protection and isolation layer to extend graphite component life, improve radial temperature uniformity, maintain SiC sublimation stoichiometry, suppress impurity migration, and reduce energy consumption.
• 1:1 wt. % Ethanol:Powder Observations • Coatings adhered to SiC substrate after sintering. • When LiCO 3 was used as a sintering aid, coating uniformity was inadequate for continued testing. 150 μ m 200 μ m Most of the mullite/BSAS coating ablated off of

RE: Si coating on SiC Hi, One possible alternative is to use spark deposition process, using low voltage(50V) and low capacitance(30 microfarad) for thin smoth deposit of Si.For futher info, please check on my book on adv.surface enginering, chapter11.

However, despite using SiC powder with an average size of 36.6 μm, which is larger than the commonly used powder (0.08‐2 μm), a coating layer was formed in this study. In addition, a unique microstructure with a crystallite distribution of 1‐5 μm, smooth surface, and smooth interface between the substrate and coating layer were characteristics that were observed.
The Al5056/SiC composite coatings were prepared by cold spraying. Experimental results show that the SiC content in the composite coating deposited with the SiC powder having an average size of 67 μm (Al5056/SiC-67) is similar to that deposited with the SiC powder having an average size of 27 μm (Al5056/SiC-27). The microhardness and cohesion strength of Al5056/SiC-67 coating are higher than
