An average growth rate of SiC at 3.4‐28.5 μm/min can be achieved via continuous hot‐wire CVD method with input powers of 300‐380 W. Raman spectroscopy, X‐ray photoelectron spectroscopy (XPS) analysis, and X‐ray diffraction (XRD) method, combined with scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were applied to investigate the microstructure of deposits. At 300 W, amorphous SiC and Si were main products in deposit, which were rapidly replaced by crystallite SiC containing high density stacking faults at 340 W and above. Moreover, with the grain size of SiC increasing from ~25 to ~420 nm, the stacking faults probability decreasing from 0.179 to 0.125, as well as the surface morphology changed from loose‐packed granules to a well‐defined faceted structure with strong (111) texture. Structural changes led to the increase of deposit's Young's modulus from 266.3 to 341.5 GPa, and the mean tensile strength of SiC filament from 1.57 to 3.03 GPa. The successive growth of W/SiC interfacial layer above 360 W resulted in the reduction in mean tensile strength and Weibull moduls of SiC monofilaments, which agrees with the prediction from critical interfacial layer thickness theory.

“…Depending on the titanium alloy used as the matrix material, TMCs can offer high specific strength and stiffness at temperatures up to 600°C [1]. Over the last two decades, various production routes have been studied by several institutions [2]. The most prominent methods are the foil-fibre-foil (FFF) process and monotape techniques (e.g.…”

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.

“…So far, however, the use of these high performance materials is still very limited due to difficulties in manufacturing and high production costs [1]. Several production routes have been investigated [3] e.g. the foilfibre-foil process or powder-based processes [4] which all include a pressure-based consolidation step.…”
