The metal matrix composites can be described as materials whose microstructure comprises a continuous metallic phase into which a second phase (ceramic materials) has been artificially introduced during processing, as reinforcement. 

The criteria for designing fibers for use in ceramic matrix composites (CMCs) are different from those for designing fibers for use in poiymer or metal matrix composites. The key properties are thermal stability and mechanical properties at high temperatures [43]. As a consequence, relatively coarse microstructures are obtained at elevated temperatures, corresponding to somewhat lower failure strengths (-2 GPa), but high thermal stability and creep resistance are preferable to ultrafine microstructures.

Unpredictable interactions can result between wear and corrosion when the surfaces in contact have complex, multiple-phase microstructures that can lead to microgalvanic activity and selective phase corrosion (a localized attack), as well as three-body wear modes. Examples of such surfaces include composites or surfaces that undergo compositional changes induced by tribological interactions. For instance, the presence of carbides in a metallic surface, typically formed for improved wear resistance, establishes a microgalvanic corrosion cell as the carbide is likely to be cathodic with respect to the surrounding metallic matrix [4]. This can result in a preferential anodic dissolution of the metallic matrix close to or at the matrix/carbide interface, and thereby accelerate carbide removal from surfaces and reduce the antiwear properties of the surface. 

AFCOP) In this technique for making multiphase ceramic matrix composites, an active filler material (a transition metal or compound thereof which will yield a carbide or other ceramic) is mixed with an organometallic polymer and pyrolysed. The kind, content and structure of the filler control the kinetics of the polymer pyrolysis and the resulting microstructure, which may contain disordered or glassy areas. (M. Seibold and P.
