Tribological Characteristics of Aluminum with Volumetric Fractions of Nano-Boron Nitride Composites

The tribological characteristics of aluminum metal matrix with different volumetric fraction of boron nitride nano-powder reinforcement were studied. The various volumetric fractions are 0.6 vol.% BN, 1.2 vol.% BN, and 1.8 vol.% BN which are added with pure aluminum. In each composition, specimens are prepared and tested on pin on disc wear testing machine for three different load conditions and three different sliding velocity conditions with sliding distance of 1000 m. The study suggests that 0.6 vol.% of BN with aluminum provides better wear resistance when compared with other compositions and pure aluminum.
