WEAR PERFORMANCE OF AL/B4C /TIC HYBRID METAL MATRIX COMPOSITES

In general, aluminium alloy components are light in weight and widely used in general engineering applications. But, they lack in good resistance to wear, particularly under poor, partial or boundary lubricated conditions. With solid lubricant particles dispersed in the matrix of aluminium alloy, this material exhibits good potential for resistance to wear and consequently, becomes more suitable for tribological applications. Aluminum based Metal Matrix composites (MMCs) have become a very valuable addition to the field of newer materials for high performance tribological applications.Aluminium based composites are being increasingly used in automobiles, aerospace, marine and mineral processing industries. Aluminium matrix composites are normally processed by the liquid casting technique or powder metallurgy route. Because of these advantages hybrid metal matrix composites (HMMCs) are using alternatives for industrial applications. Among the metal matrix composites, aluminium based composites are received attention of researchers due to its unique characteristics.
