Abstract
The tribological characteristics of aluminium metal matrix with different weight fraction of titanium dioxide nanopowder reinforcements along with 0.5 wt% of boron nitride nanopowder reinforcement were studied. The various weight fractions of reinforcements are 0.3 wt% TiO2 + 0.5 wt% BN, 0.5 wt% TiO2 + 0.5 wt% BN, and 0.7 wt% TiO2 + 0.5 wt% BN are added with pure aluminium. In each composition, specimens are prepared and tested on pin-on-disc tribometer for three different load and sliding velocity conditions with constant distance. The study suggests that 0.3 wt% TiO2 + 0.5 wt% of BN with aluminium provides better specific wear rate and coefficient of friction.
