Methods for producing a transition-metal-coated carbon material having a transition metal coating which has a high adhesion strength between the transition metal and the carbon material, and which is neither exfoliated nor detached in subsequent processing are provided. The transition-metal-coated carbon material may be obtained by adhering a compound containing transition metal ions onto a surface of a carbon material and by reducing the transition metal ions with carbon in the carbon material by a heat treatment, thereby to form elemental transition metal. Here, the transition metal is Fe, Co, Ni, Mn, Cu or Zn. Moreover, also provided is a carbon-metal composite material exhibiting an excellent mechanical strength and thermal conductivity, by improving affinity with a metal such as aluminium by use of the transition-metal-coated carbon material.

A ceramic matrix composite component and methods of making are described herein. The ceramic matrix composite may include a silicon containing matrix and refractory fibers embedded within the silicon containing matrix. The ceramic matrix composite component may further include a silicide layer sandwiched between the silicon containing matrix and the refractory fibers. A method of forming a ceramic matrix composite may include infiltrating a fluid that includes a refractory metal element containing compound into a fiber preform that includes fibers. The method may further include depositing the refractory metal element from the refractory metal element containing compound onto the fibers and forming, from the refractory metal element deposited onto the fibers, a refractory metal silicide.
