Tribological properties of Zircon sand and Zirfloor reinforced LM13 alloy matrix composite-A comparative study

The tribological behaviour of samples of LM13 alloy matrix reinforced with 15 wt. % Zircon sand also 15wt.% and Zirfloor particles in low and high range of loads (1kg and 5kg) was determined using a pin-on-disc wear and friction monitor at a constant velocity of 1.6 m/s. Zircon sand and Zirfloor sand (particles size 5-32μm) are reinforced in the LM13 alloy by stir casting method. Optical microscopy show uniform distribution of particles and reveal better bonding in the case of zircon particles reinforced composite compared to that in zirfloor particles reinforced composite. It is observed that the zircon particle reinforced composite shows relatively better wear resistance property compared to zirfloor-reinforced composite.
