“…The PVD method is not suitable for coating of complex-shaped substrates (e.g. carbon fiberbased textile preform) because it is a line-of-sight process [20]. In the case of electroless coating, the method is generally limited to metal deposition (e.g.…”

“…The demands on coating materials are already listed by Reischer et al [9] and Feldhoff et al [10]: (i) to provide an adequate fiber-matrix adhesion and (ii) to act as a diffusion barrier and thus to maintain the fiber strength. Different deposition technologies for applying protective coatings were described in the literature such as chemical solution deposition (sol-gel technique) [11][12][13], chemical vapor deposition (CVD) [14,15], physical vapor deposition (PVD) [16] electroless deposition [1,17,18] and molten salt method [19,20]. The PVD method is not suitable for coating of complex-shaped substrates (e.g.…”

“…To overcome these problems, we proposed a molten salt method in previous papers to synthesize TiC coatings on carbon fibers at a relatively low temperature [9,10]. This method uses a molten salt medium composed of LiCl-KCl-KF to transport a carbide forming element (Ti or TiH 2 ) to the surface of each individual filament in the fiber bundle, whereupon it reacts with carbon and forms a uniform and continuous TiC coating on each carbon fiber filament.…”

induces an increase in the total surface free energy of the carbon fibers, and as a result the wettability of carbon fibers with molten Mg and Al is improved remarkably. TiC coating is found to be stable at 1000°C in molten Mg. However it is readily decomposed by the molten Al at high temperature, which brings about carbon fibers being attacked by the molten Al.and the consequent severe damage of carbon fibers.

“…However, few works deal with the preparation of metal carbide coating on Gr f s using molten salts method. Although TiC coating on carbon fibers has been successfully produced using molten salts method and proven to be effective in improving wettability of carbon fibers with molten Al [23,24], there is no detailed investigation on the thermophysical properties of Gr f /Al composites. Therefore, the present study is focused on enhancement of thermal properties of Gr f /Al composites with chromium carbide coatings.…”

A chromium carbide coating was synthesized onto graphite fibers by molten salts method to improve the interfacial bonding and thermal properties of short graphite fiber/Al composites which were fabricated by vacuum pressure infiltration technique. The graphite fiber/Al composites with different thicknesses of chromium carbide coatings were prepared through varying plating times to investigate the influence of chromium carbide layer on the microstructures and thermal properties of the composites. The combined Maxwell-Garnett effective medium approach and acoustic mismatch model schemes were used to theoretically predict thermal conductivities of the composites. The results indicated that the chromium carbide coating formed on graphite fiber surface in molten salts consists mainly of the Cr 7 C 3 phase. The Cr 7 C 3 -coating layer with plating time of 60 min and thickness of 0.5 lm was found to be most effective in improving the interfacial bonding and decreasing the interfacial thermal resistance between graphite fiber and aluminum matrix. The 40 vol% Cr 7 C 3 -coated graphite fiber/Al composite with Cr 7 C 3 thickness of 0.5 lm exhibited 45.4 % enhancement in inplane thermal conductivity of 221 W m -1 K -1 compared to that of uncoated composite, as well as the coefficient of thermal expansion of 9.4 9 10 -6 K -1 , which made it as very interesting material for thermal management applications.
