The Effects of Applied Load on Wear Behavior of Al-Quarry Dust Particle Composite Disc Sliding against Automobile Brake Material

Abstract:

The wear behavior of aluminium alloy (A356) reinforced with 5 wt. % of quarry dust particles composite disc was sliding against automobile brake friction lining pin was investigated. Dry sliding wear studies were investigated in pin-on-disc apparatus. The wear tests were carried out range of applied load 20 to 60 N and constant sliding velocity (0.5 m/s) under sliding distance of 500 m. The wear behavior of aluminium metal matrix composite (AMC) has been compared with the commercially used 25 grade Gray Cast Iron disc (GCI).The results showed that the wear rate of AMC disc decreased with increasing the applied load. However the wear rate of AMC disc with respective pin decreased with increasing the applied load. The coefficient friction increased with increasing the applied load. The scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDAX) used to investigate the disc and pin. The wear debris was analyzed by SEM image.
