Deposition of titanium on SiC fibres from chloride melts
The present study examined the feasibility of producing titanium matrix composites based on a molten salt fibre coating process. It is demonstrated that sufficiently thick and coherent titanium coatings can be deposited on SiC fibres in LiCl-KCl-TiCl(2) at 700 K. One important aspect of the study was the behaviour of the substrate during electrolysis. Therefore, additional features related to carbon-coated SiC fibres and carbonaceous substrates in general are outlined. The morphologies and microstructures of electrolytically coated SiC fibres were investigated by scanning electron microscopy and compared to fibres coated by a physical vapour deposition technique. The cause and relevance of the growth failures that were observed in this study are also discussed.
