Novel synthesis of SiC coating by liquid phase deposition

In this study, SiC coating was prepared on carbon fibres from solution at ambient temperatures for the first time. The thickness of the coating was ∼85 nm. Analysis of the coatings revealed the presence of only SiC in the coating. The initial oxidation temperature of the SiC-coated carbon fibres increased by ∼50°C and the complete oxidation temperature was increased by ∼167°C, indicating excellent oxidation resistance owing to the presence of the SiC coating. We believe that the excellent properties and easy preparation process of SiC coating reported in this paper would provide us with a new way to produce SiC coating on carbon substrates.
