Study of wear mechanism for LM13/Zr composite under dry sliding conditions at different loads

In the present paper, well known piston alloy (LM13) reinforced with ZrSiO4 particles was developed and studied as wear resistant material. The particle reinforced aluminum metal matrix (PAMC) was developed by stir casting route. Composite was developed by reinforcing 10 wt. % of ZrSiO4 particles into LM13 alloy. Wear behavior of LM13 alloy reinforced with ZrSiO4 particles have been carried out with different applied load. Micrographs of worn surfaces after wear test were examined by scanning electron microscope. These micrographs indicate the presence of the adhesive and abrasive wear mechanism, and transition from mild to severe wear at higher load.
