Carbon fiber or fabrics are century old engineering materials, which were first produced by Edison for their use in electric lamps and also as electrical conductors . Its increasing use in metal matrix composites (MMCs) has made this material more popular as an engineering material. The interfacial chemical reaction between the carbon fiber with the matrix affects the MMCs performance irrespective of the synthesizing routes adopted. The better wettability of fibers/fabric with the matrix has been considered of utmost importance . The non-wetting of dispersoid with the matrix can lower the performance of the composite as a result of discontinuity at the interface. One of the ways to get rid of these difficulties is by coating the fibers/fabric. It can be said that the metallic coatings improve metallurgical characteristics like wear resistance, corrosion resistance, mechanical strength in general and also improve the wettability characteristic of fabric. It is also possible to attain the distinct properties to MMCs by giving suitable heat treatment after coating or by the addition of alloying elements in the matrix of the alloy . The nature of nickel base EL coatings is well understood and they are easy to process . The performance of MMCs largely depends upon the morphology of the less common phases present in the coatings, thickness and nature of the coatings .
