Prediction of wear coefficient of Al6061–TiO2 composites

In recent years, aluminum alloy based metal matrix composites (MMC) are gaining wide spread acceptance in several interesting applications such as piston, connecting rod, microwave filters, vibrator component, contactors, impellers and space structures. These composites possess excellent wear resistance in addition to other superior mechanical properties such as strength, modulus and hardness when compared with conventional alloys. Of all the aluminum alloys, 6061 is quite popular choice as a matrix material to prepare MMCs owing to its better formability characteristics and option of modification of the strength of composites by adopting optimal heat treatment. From the literature, it is quite evident that the focus has been centered on processing of MMCs and characterization of mechanical properties of MMCs.
