Abstract
The tribological behavior of Dual Particles Size (DPS) rutile reinforced LM13 alloy composite was investigated under varying applied pressure from 125 kPa to 625 kPa at a constant sliding speed of 1.6 m/s. In the present studies, 15 wt.% of rutile particles of different sizes (50–75 μm and 106–125 μm) are reinforced in the Al-12Si alloy (LM13) by liquid metallurgy route. Micro-hardness of the prepared samples was measured in different phases. Microstructure, wear mechanism and surface morphology of the wear surfaces and debris was observed under optical and scanning electron microscope. The change in wear behavior has been explained with reference to the observed EDS analysis of the wear track and debris. However, an interesting change in wear feature, mild to severe wear transition at critical pressure was noticed in wear behavior of the composite. The Al-DPS composite has immense potential to be used as a component material for tribological applications.
