Wettability in Metal Matrix Composites

Metal matrix composites (MMCs) have been developed in response to the enormous demand for special industrial materials and structures automotive aerospace applications, wherein both high-strength light weight are simultaneously required. The most common, inexpensive route fabricate MMCs or metal nanocomposites (MMNCs) is based on casting, reinforcements like nanoceramics, -carbides, -nitrides, elements carbon allotropes added molten matrices; however, of mentioned reinforcements, especially those with nanosized reinforcing particles, usually poor wettability serious drawbacks particle agglomerations therefore diminished mechanical strength almost always expected. Many research efforts made enhance affinity between mating surfaces. aim this paper critically review comprehensively discuss approaches/routes commonly employed boost wetting conditions at reinforcement-matrix interfaces. Particular attention paid aluminum owing interest lightweight need properties strength, wear, creep resistance. It believed that effective treatment(s) may enormously affect interfacial strength.
